Do you regularly check underneath your bed? You might want to do that a little more often, because some strange things are found there.

1. The man who found a crocodile underneath his bed

You've probably heard the song, “Crocodile Rock” but this, my friends, is a case of crocodile shock!

In 2013, Guy Whittall was spending the night at the Humani Ranch in Zimbabwe. The former cricket player slept for a blissful 8 hours without even realizing that he had an unexpected guest relaxing under his bed. He even recalled hanging his feet over the side of his bed for some time in the morning and was completely unaware of how close he was to becoming a crocodile's snack.

Whittall, who currently serves as director of the family-owned lodge, was having breakfast in the kitchen when he heard the bloodcurdling screams of his maid, who discovered the 330-pound reptile underneath the bed. He immediately called in some of his co-workers who helped remove the crocodile from the room and release it back into the nearby Humani Chigwidi dam.

Although Whittall was surprised by his unwanted reptilian houseguest, he reckoned the locals are used to this type of thing. “I just remember thinking goodness gracious, that's one for the books. I'm pretty sure everyone in Humani checks under their bed before going to sleep now anyway.”

2. The man who kept Napoleon's penis underneath his bed

Napoleon Bonaparte was a legendary military genius and the emperor of France. His quest for military expansion changed the world. By 1810-1811, his empire ruled pretty much all of Europe, and he held alliances with Austria, Russia, Denmark, Sweden, and a greatly reduced Prussia.

The strange journey of Napoleon's body parts, including his penis, seemed to cover almost as much ground.

In 1821, after Bonaparte died, Dr. Francesco Antommarchi performed an autopsy on the first emperor of France and removed his liver and stomach, and placed them in jars of ethyl alcohol. The doctor also removed Napoleon's penis and gave it to a priest in Corsica.

The penis was not preserved. It shriveled enough to resemble a piece of leathery beef jerky.

In 1916, the “mummified tendon” went on the auction block where a British collector bought it. In 1924, an American collector bought it for £400. The penis went on display at the Museum of French Art in New York.

In 1977, a urologist living in New Jersey purchased the phallic relic for $3,000 and stored it under his bed until he died 30 years later.

His daughter inherited the penis and has since received an offer of $100,000 for Bonaparte's manhood.

3. The decomposed body that was under a bed in a motel room

You might have heard the story of a couple checking into a hotel/motel room, putting up with a foul stench and, ultimately, finding a decomposed body underneath a bed in the room. That tale has been an urban legend for years but in several cases, along with being creepy, it's been proven true. In fact, it has been reported more often than you would think in hotel/motel beds in Las Vegas, NV, Pasadena, CA and several places in Florida and Kansas City, MO.

Especially gruesome was the discovery of a dead body stuffed under a mattress in a room found by the cleaning crew at the Capri Motel in Kansas City, Missouri in July 2003.

Local news station KMBC-TV reported that police said that the man appeared to have been dead for some time, but the body went unnoticed until a guest staying the room could no longer tolerate the smell. Police reported that the hotel's cleaning staff lifted up the mattress in the room and found the body and suspected that the wooden panels on the side of the bed prevented someone from discovering it earlier.

4. The woman who found a sinkhole under her bed

In what seems like a scene out of Nightmare On Elm Street, Guatemala City resident Inocenta Hernandez awoke to the sound of a loud explosion one morning in July 2011. Hernandez originally thought the sound was caused by cooking gas tank explosion or a car accident outside.

After peeking out to see where the noise originated from, a neighbor told her that the loud noise came from inside of her house. She soon discovered, to her horror, a three-foot-wide, 40-foot-deep sinkhole beneath her bed. This wasn't even the biggest sinkhole reported in the area. A larger, 330-foot-deep sinkhole formed nearby in 2007 and left three people dead.

Hernandez counts her blessings. “Thank God there are only material damages because my grandchildren were running around the house, into that room and out to the patio."

A sinkhole is formed due to natural underground erosion. Most of the time, the collapse is very sudden.

5. The woman who searched for her cats under her bed but found a human instead

In March 2015, a stranger was knocking on residents' doors in the Cayman Drive area of Palm Springs, Florida. A neighbor watched as the man walked toward the rear of a residence and who immediately phoned police.

Simultaneously, a 61-year old resident of that very home was looking for her cats when she reached under the bed and, instead of feeling fur, she “touched human skin.”

That caused the man, later identified as Christian Vatovec, 25, to flee from the home and jump a fence before running west where police caught him.

Vatovec faces burglary, grand theft and resisting arrest charges. A cat burglar Vatovec is not.

6. The meth dealer who had a series of escape tunnels under his tanning bed

In December 2014, local police in Milledgeville, Georgia arrested 36-year-old Shane Cox for selling methamphetamine. Cox had a long rap sheet and was under surveillance for months before police finally arrested him.

The police commander called in the bomb squad to assist in the search. Bomb sniffing canines helped investigators search for explosive devices and booby traps inside the house. In addition to methamphetamine and gunpowder found in the house, agents also discovered a six-foot hole under a tanning bed connected to two tunnels and a trap door under a living room chair. This lead to several rooms where Cox often hid from law enforcement.

He was arrested at a local Dollar General store shortly before the raid. Nobody knows for sure if he bought supplies at the Dollar General store to help aid in constructing his amazing labyrinth but if that's the case, who the hell was this guy? MacGyver?

7. The landlord who discovered almost $1 million dollars underneath the bed of an ex-tenant

Some people find crocodiles under their beds, others find cash – lots of cash. In October 2013, Landlord Ma Guangdi was cleaning up after one of his former tenants in an apartment in Dongguan, Guangdong Province, China when he made an incredible discovery. Underneath one of the beds in the apartment, Guangdi found he found 6.33 million Chinese (about ($892,000) Yuan in cash, left behind in boxes.

The occupant had been a tenant for several years, had simply disappeared and had stopped paying rent.

When he was cleaning the apartment for the next possible tenant to move in, Ma discovered four carton boxes completely stuffed with cash.

The money has been placed in a safety account box while police investigate the former tenant.

8. The world's most valuable violin spent five decades underneath a bed

The Vieuxtemps Guarneri is the crème de la crème of violins. This 274-year-old violin is also the most valuable in the world, recently selling for an estimated $16 million. The anonymous new donor unselfishly realized that the musical instrument was best kept in the hands of world-renowned violinist Anne Akiko Meyers, who has the violin on loan for the rest of her life. The instrument, which dates from 1741, is named after its most famous owner, the leading 19th-century Belgian virtuoso and composer Henri Vieuxtemps, who loved it so much he wanted to be buried with it.

During its long history, the stringed instrument was played by some of the most renowned violinists including Itzhak Perlman, Henri Vieuxtemps and Yehudi Menuhin, before being stored under the bed of the previous owner for five decades.

Dubbed the Mona Lisa of Violins, it has become a favorite game of aficionados to compare the creations of Antonio Stradivari with his younger rival, Guarneri.

Now, after decades of languishing under a bed, Meyers has “awakened” the violin for further generations to enjoy.

9. The poltergeist that terrorized a couple turned out to be a meth head

Sometimes, there really is a boogeyman under the bed.

Just ask Brian O'Neill and his wife Bridgett, who returned to their Seattle condo late one night in July 2014 to discover their clothes scattered everywhere, electronics piled up high on their bed. Strangest of all, the soles from 20 pairs of shoes had been removed. Nothing had been stolen, save for $50 in cash. They also found a purse containing a 27-year-old woman's ID card that had mysteriously appeared on top of the their bed.

The couple called the police. They found nothing, not even fingerprints. The city of Seattle website described the incident as the scene looking like “a poltergeist rampage” with the police finding “remnants of apparent paranormal activity.”

Right after police left, the O'Neills called them again. This time they heard noises coming from under their bed.

When the police returned they didn't find a monster, but a meth addicted woman under the bed, hiding for hours with a kitchen knife. Later, they also found a hypodermic needle in the sheets, and locks of golden hair littered throughout their condo.

Bridgett O'Neill said, “Rather than use the knife to pop out and murder us, she was using it to deconstruct the box springs of the bed. Honestly, I feel kind of bad for her. This woman was so tiny and not together, it's hard to be mad.” Let's hope the under-the-bed dweller found the help she needed.

10. The spray that gets rid of monsters under your bed

We've all heard about or have seen the kid who couldn't sleep because the boogeyman was hiding underneath his bed. That kid could have been you or me. One such kid was 6-year-old Madalynn Greenhaw of North Dakota.

Madalynn's mother said that the young girl developed a fear of a green monster with sharp nails and scary ears that liked the smell of garbage, which prevented her from nodding off.
Now young Madalynn sleeps like a log thanks to non-medicated spray called Monster Spray.

The spray, developed by pharmacist Jeff Dodds and his daughter Josslyn, is made from blue food coloring and water. Each batch allows for 120 sprays and comes with its own prescription, instructing: “Spray around the room at night before bed, repeat if necessary.”
