Little Johnny joke

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 away."

"Well the answer is four" said the teacher, "but I like the way you are
thinking."

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

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

"No," said Little Johnny, "the one with the wedding ring on her finger, but
I like the way you are thinking."
