There Are No Poisonous Cows, Mom

Little boy pointing to portabella mushroom: Mommy, what's that?
Tired mother: It's a mushroom. Someday I'm going to make you a hamburger for dinner, but instead of meat, it's going to have one of those mushrooms in it.
Little boy looking back at mushroom, terrified: Why would you do that?!
