I pushed my friend into the girl's toilet once. He tripped and fell. Stunned for a second...fixed his glasses. Realised where he was standing. Screamed. I got beaten up by him.
But he probably enjoyed the experience because some girls were changing in there.
My cousin's friend was a heavy smoker and he kept smoking in the toilet. Once the teacher came while he was smoking. So he quickly threw away his cigarrete when the smoke was still in his lungs. The teacher asked him "were you smoking?" and the guy just had to say "no" with all the smoke coming out from his mouth. :roll: but my cousin says that after the few years they started smoking together.
