Bedtime Conversation

Benny: What is WRONG with my tummy?
Me: I don't know. Does it hurt?
Benny: Yes. I think I ate too much.
Me: Well, I think you are growing.
Benny: GREAT! That means that soon my skin will be coming off!
Me: WHAT?!?!
Benny: Don't worry, Mommy. It only comes off a tiny bit at a time, and more grows in underneath.
Me: Do you remember what the skin cells are called?
Benny: Emmetherer?
Me: Epithelial.
Benny: Thelial. That sounds like STOP THIEF! Like a stone thief, or a rock thief, of a car thief, or a HUMAN THIEF.
Me: Wow.
Benny: I hope a human thief doesn't come and try to get ME because I will LASER HIM. And if he runs really fast and he's too fast for me I will need you and Daddy to say those words: STOP THIEF. Will you do that?
Me: Sure.
Benny: Thanks.
