This one isn't funny so much...just consider it a slice of life in my class this year.

Violet: (Very whiny) Mrs. Beeeee! Joey just wiped a booger on my desk.

Mrs. B: (Not believing) Seriously, Violet, you've GOT to stop the tattling on...(sees a HUGE booger on Violet's desk) AHHHHH!!!!! Joey!

Joey: What! I didn't do it.

15 other witnesses: Yes you did!!!

Mrs. B: (Trying to be calm) Joey. (Takes deep breath) Please get a Clorox wipe and clean Violet's desk. And to the rest of you, let's just assume that from now on, wiping boogers on someone else's desk is NOT allowed.
