I have to share this story, it made going back to work today a little less painful! Here is the conversation that took place 8th period
Female student: Ms. Davidson, what's an anus?
Me: Ask your science teacher!
Male student: You really don't know what an anus is? It's another word for your bellybutton
Me: *laughter* *laughter* it seems you're the one who doesn't know what an anus is! *laughter* *laughter*
Female student #2: It's your butthole!
Me (to male student): I think you're thinking of the word "navel".
Male student: Oh right.
