So there's this guy walking to school and on his way there he sees these two girls talking to each other. He drops in on their conversation and hears them talking about a purple flower. He thought to himself "Purple flower?" and stops to think about it. 10 minutes later, he realizes he's late for school and runs as fast as he can. So he gets to class and the teacher asks him, "Why are you late?"
The guy says, "Well...I was walking to school and heard two girls talking about a purple flower, stopped to think about it, and realized I was late to school, and now I'm here!"
The teacher replies, "What?! Purple flower?! You're going to the Dean's
