From FuzzOnWall:
What does a kiss taste like? One day a teacher had a taste test with her students. She picked a little boy to do the first test. She blindfolded him, put a Hershey kiss in his mouth and asked, “Do you know what it is?”

“No, I don’t,” said the little boy. “Okay, I’ll give you a clue. It’s the thing your daddy wants from your Mom before he goes to work.”

Suddenly, a little girl at the back of the room yelled, “Spit it out! It’s a piece of ass!”
