Fun Things To Do In A Public Bathroom

Using a small squeeze tube spread peanut butter on a wad of toilet paper and drop the wad under the stall wall of your neighbor. Then say, "Whoops, could you kick that back over here please?"
Fill a balloon with creamed corn. Rush into the stall with your hand over your mouth and let out a lengthy vomit impression while you squeeze the balloon and splatter cream corn all about. Apologize profusely and blame it on the fettuccine alfredo you had for breakfast.
Take in a wineskin filled w/ water. Stand and slowing squeeze it out into the toilet, every 15-20 seconds moan or sigh.
Say, "Boy, that sure looks like a maggot."
Before you unroll toilet paper, conspicuously lay down your "Cross-Dressers Anonymous" newsletter on the floor visible to the adjacent stall.
Lower a small mirror underneath the stall wall, adjust it so you can see your neighbor and say, "Peek-a-boo!"
Stick your open palm under the stall wall and ask your neighbor, "May I borrow a highlighter?"
Cheer and clap loudly every time somebody breaks the silence with a bodily function noise.
Say, "Hmmm, I've never seen that color before."
Grunt and strain real loud for 30 seconds and then drop a cantaloupe into the toilet bowl from a height of 6 feet. Sigh relaxingly.
Say, "Now how did that get there?"
Say, "Interesting... more floaters than sinkers."
After flushing Say, "Darn, I knew that drain hole was a little too small. Now what am I gonna do?"
Fill a large flask with Mountain Dew. Squirt it erratically under the stall walls of your neighbors while yelling, "Whoa! Easy boy!"
