superdeluxe, eating an Avada Kedavra egg is when Logic and OCD go to war!
Logic: The egg did NOT come out of Avada Kedavra's butt. It exited her vent.
OCD: Vent is just a fancy scientific term for butt! BUTT! It came out of her butt! The shell is covered in germs and now I am, too!
Logic: You do not eat the shell. You can wash the shell. The egg is fine, and you're being neurotic.
OCD: BUTT! BUTT! BUTT! GERMS!
Logic: Make Lady Friend an Avada Kedavra omelet and yourself a store omelet, which also came out of a chicken's VENT.
OCD: I win!
Logic: Only this round, OCD. I'll be back tomorrow.
