Where does meat come from?

At dinner tonight we were talking to Abby about where certain things come from so I asked her:

"Where do eggs come from?"
"Chickens!"
"Good, Ab."

"Where does honey come from?"
"Hmm... bees!"
"Great job!"

"Where does milk come from?"
"Cows, cows!"
"You are so smart."

"OK, where does hamburger come from?"
Without missing a beat... "McDonalds!"

I think Adam spit milk out of his nose we were laughing so hard. She didn't quite get what was so funny, but repeated it over and over anyways. Kids are so funny.
