The horrors of sex education

A teacher asks her class, "If there are 5 birds sitting on a fence and you shoot one of them, how many will be left?" She calls on little Johnny. He replies, "None, they all fly away with the first gun shot" The teacher replies, "The correct answer is 4, but I like your thinking."
Then, Little Johnny says "I have a question for YOU. There are three women sitting on a bench having ice cream: One is delicately licking the sides of the triple scoop of ice cream. The second is gobbling down the top and sucking the cone. The third is biting off the top of the ice cream. Which one is married? "The teacher, blushing a great deal, but finaly replied "Well I suppose the one that's gobbled down the top and sucked the cone" To which LittleJohnny replied:
"The correct answer is the one with the wedding ring on, but I like your thinking."
