Last night while standing next to one of my students at the earthworm kill station:
Her: Is the earthworm the biggest thing we have to kill this semester?
Me(lying through my teeth): No.
Her: It's not? What else is there?
Me: You have to kill your own fetal pig.
Her (clearly not getting it): Seriously?
Other Students: *Giggling*
Me (deciding to take it way too far): We also dissect a human baby, and you're going to have to kill that yourself too.
Her: Don't say that. My sister just had a baby.
Me: Well then you're in luck! Because of the budget cuts, you're going to have to supply your own, but it looks like you won't have to look very hard. You can just use your sister's.
Her: You're terrible.
Me: Ok, fine. The earthworm is the only thing you have to kill yourself this semester.
