Little Johnny was sitting in class doing math problems when his teacher picked him to answer a question:

"Johnny, if there were five birds sitting on a fence and you shot one with your gun, how many would be left ?"

"None.", replied Johnny. "'cause the rest would fly off."

"The correct answer is four," said the teacher. "But I like your thinking."

Little Johnny said, "I have a question for you now. If there were three women eating ice cream cones in a shop, one licking her cone, the second biting her cone, and the third one sucking her cone, which one is married ?

"Well," said the teacher nervously, "I guess the one sucking her cone?"

"No," said Little Johnny, "The one with the wedding ring on her finger. But I like the way you think!"
