Toilets are musical – rumor has it the great majority of them will flush in the key of E flat.

Separate mens and ladies toilets didn’t start until a high society party in Paris made it fashionable in 1739.

The US spent over $100,000 on a study to determine how people hung their toilet paper – flap in front or behind. The results: 3 out of 4 have the flap in front.

The first toilet was shown on the television show Leave It To Beaver. The first flushing toilet was shown in the movie Psycho. And as you can imagine, the scene in Psycho caused an enormous amount of complaints about indecency.

The first toilet cubicle in a row as you enter a facility will be the least used, and therefore the cleanest. (Have you ever been almost the only person in one of those giant public restrooms, tons of cubicles, and someone comes in and chooses the cubicle right next to you?)

The first commercial roll of toilet paper was produced in 1890 by Scott Paper Company. It looked much as we know it today.

Everybody has their own word for the toilet. Here are a few: loo, powder room, dunny, bog, khazi, necessary, potty, privy, latrine, place of easement, little girls room, little boys room, and of course the throne room.

The average desk contains 400 times more bacteria and germs than the average toilet seat.

Over 40,000 Americans are injured by a toilet every year.

An average person visits the toilet 7 times a day, 2500 time a year, and 200,000 times in a lifetime.

Travel note: if you are ever in Las Vegas, check out the restrooms at the Paris casino and convention center because the PA system gives racy French lessons:

Here are some of the English phrases they translate into French for you (Ladies Room version):

- "Your clothes would look great on my bedroom floor."

- "Do you believe in love at first sight? Or should I walk by again?"

- "Has anyone seen my panties?"

- "If my husband calls, I'm not here."

- "Where is my wedding ring?"

- "I shaved my legs for this?"

- "Oh la la. I'm never drinking again."
