"Okay, class, let's start with the letter A."
        Johnny raises his hand.
        "Susie," the teacher calls.
        "A is for apple. Apples grow on trees," she replies.
        "Very good," the teacher says. "Okay, class, let's do the letter
B."
        Johnny raises his hand excitedly.
        "Mikey," the teacher calls.
        "B is for baseball. Baseball is my favorite sport."
        "Very good," the teacher says. "Okay, class, let's do the letter
C."
        Johnny raises both hands! He's going nuts! He's got the perfect
word for C!!
        "Bobby," the teacher calls.
        "C is for cat. A cat lives in my backyard."
        "Very good," The teacher says. This goes on and on, and the

teacher is not going to call on Johnny if there's a cuss word that starts with the letter she calls out. Finally, she gets to the letter R. The teacher can't think of a single cuss word that starts with R, and even Johnny looks a little puzzled. So she calls out R and asks Johnny to respond.

Johnny nervously stands up. He looks around the room. Then he says "R is for a Rat..." he suddenly gets excited and stretches both arms wide, "...a rat with a dick this big!"
