A lady goes into the butcher shop and as she is walking around the store, she spies a beef tongue in the butcher's counter. The lady asks, "What in the world is that?"

"Beef tongue," replies the butcher!

The lady gives a little involuntary shudder, "Ewww! Gross! No way would I put anything in my mouth that came out of an animal's mouth!"

The butcher nods sympathetically while peeking into the woman's shopping cart, "I see you're buying a dozen eggs!"
