Random Conversation: Inventing Cows

Noah: I'm glad cows were invented, or we would never have milk.
Nat: You're wrong. What about goat milk? Sheep?
Noah: Oh yeah. But really, who would put goat milk in cereal? Gross.
Dad: Right. By the way, who invented cows anyway?
Nat: G-d, of course.
Noah: Who invented G-d?
Dad: Interesting question there.
Noah: Who invented G-d's grandmother also?
