A Kindergarten teacher was giving a lesson to her pupils, and she asked them, "Ok, if three birds are sitting on a fence, and I shoot one, how many are left?"
One of the boys raised his hand and the teacher called on him, "None," he answered. "No, I'm sorry, the answer is TWO," the teacher replied. "But," returned the boy, "if you shot at one bird, wouldn't the other two fly away?" "Well, that's still not the right answer," began the teacher, "but I like the way you think!"
"Ok, now I have a question for you," started the boy. "If three women are standing on a sidewalk eating ice cream and one is just nibbling at it, one is really licking it, and the other is shoving it deep down into her throat... how can you tell which one is married?"
"Now, I really don't like this question," lectured the teacher, "but I would have to say it is the third one." The boy glanced casually at his teacher, "Nope, it is the one wearing the ring... But," he added, "I like the way you think."
