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's kiss in his mouth and asked, "Do you know what this 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!"
