What a kiss tastes like

One day a teacher had a taste test with her students.  She picked a little boy to do the first test.  She blind folded 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 !!”
