This is a joke I got from my friend Nomxis.
There were three boys in a classroom, one called Zip, the next Willy and the other Pee. They were all in the classroom sitting, then the teacher said she had to go to the principals office, so she left. After that Zip, Willy and Pee started giving trouble and pulled up the classroom and litter, then they heard their teacher coming back so Willy jumped into the closet to hide, then Zip jumped on top of the closet thinking the teacher wouldn't see him so high, and Pee went into the corner because he didn't have anywhere to hide.
The teacher rushed into the classroom and said, Zip down, Willy out, Pee in the corner.
