Don't Erase This

One day when the teacher walked to the black board, she noticed someone had written the word 'penis' in tiny letters. She turned around, scanned the class looking for the guilty face. Finding none, she quickly erased it, and began her class. The next day she went into the room, and she saw, in larger letters, the word 'penis' again on the black board. Again, she looked around in vain for the culprit, but found none, erased it and then proceeded with the day's lesson. Every morning, for about a week, she went into the classroom and found the same disgusting word written on the board, each day's word, larger than the previous day's word. Finally, one day, she walked in, expecting to be greeted by the same word on the board, but instead, found the words: "The more you rub it, the bigger it gets!"

Juggler Test

A juggler, driving to his next performance, was stopped by the police.
"What are those knives doing in your car?" asked the officer.
"I juggle them in my act."
"Oh yeah?" says the cop. "Let's see you do it."
So the juggler starts tossing and juggling the knives. A guy driving by sees this and says, "Wow, am I glad I quit drinking. Look at the test they're making you do now!"

Spooky Love

There is an old colonial cemetery where the grave markers are flat.  A man and woman sneak in there one night after a Halloween party to make love.  The next day the woman is complaining of a terrible back ache, so she goes to see her doctor.  The doctor asks her to put on a gown and examines her back but finds nothing wrong.  He asks her how old she is, and she says 28.  The doctor says that's interesting because it says on your ass that you died in 1784.
