A group of 3rd graders was given a "taste test" at school one day. Blindfolded, the first little girl gets an apple slice and say's "Mrs. Smith, that tastes like apple". The teacher says, "Very good, Mary. You may take your seat."
The second boy gets an orange wedge and says, "Mrs. Smith, that was orange". She says, "Very good, Robert. You may take your seat."
Next up is Johnny with Billy to follow. She unwraps a Hershey's kiss and gives it to Johnny. He eats and and says, "I'm not sure what that was, Mrs. Smith." The teacher, thinking that Johnny is just trying to get another piece of chocolate decides to give him a "hint" rather than more of the delicious candy... Mrs. Smith says, "I'll give you a hint, Johnny. It's something that your mommy gives your daddy every night when they go to bed."
Billy spins around and says, "Spit it out, Johnny!!! It's a piece of ass!!!"
