What jokes did you think were hilarious when you were a kid, but make you roll your eyes now that you're an adult? [NSFW perhaps?]

For me, it's this gem...

A kid is sitting in his classroom at school, and walks up to his teacher. He asks "Will you take off your shirt?" Of course the teacher says no. The boy says "I'll cry!" So the teacher agrees.

A few minutes later the boy comes back and asks "Will you take off your skirt?" Again the teacher says no. "I'll cry!" So the teacher agrees.

The boy comes back a third time and asks "Will you take off your underwear?" The teacher says no. "But I'll cry!" So again the teacher agrees.

Finally the boy comes back one last time and asks "Can I stick a ruler up your butt?" Obviously the teacher says no. "But I'll cry!" Reluctantly the teacher agrees.

So the boy is sticking the ruler up the teachers butt, when the principal walks in the room, horrified as he sees what's going on, and says "Jeremy Uppmore!!!" And the boy says "I'm trying, I'm TRYING!"

I heard that one in grade 2. SMH
