(I win a two-liter Coke bottle in science class, but since there isn’t enough space in my locker, I ask the teacher to keep it until I can pick it up at the end of the day. When school ends, the teacher isn’t there, so I just enter his classroom and get the Coke myself. The next morning, I pop into his classroom.)

Me: “You’re a dirty liar!”

Teacher: “Uh oh…”

Me: “I told you I’d come pick up my Coke at the end of the day and you weren’t there.”

Teacher: “Okay, I’ll get it.”

Me: “No, I got it myself. But I’m getting a new Coke dealer.”
