Funny Dirty Joke

A teacher is teaching a class and she sees that Little Johnny isn't paying attention so she asks him this, "If there are three ducks on a fence and you shoot one how many are left." Johnny says none. The teacher asks why. "Because the shot scared them off" says Johnny. Johnny asks the teacher, "If you see three women walking out of an ice cream parlor, one is licking her ice cream, one is sucking her ice cream, and one is biting her ice cream, which one is married?" The teacher says, "The one sucking her ice cream." Johnny says, "No, the one with the wedding ring, but I like how you're thinking!"
