A teacher asked Little Johnny what 5 minus 2 was. He didn't know.
The teacher then said, "Suppose you have 5 birds on a wire and you shoot 2; how many are left?"

Little Johnny responded, "None."
The teacher said the answer was incorrect.

He said that if he shot 2 the other three would fly away.
The teacher said, "That still is the incorrect answer, but I like the way you think."

So then, he asked her, "Suppose you have 3 women in an ice cream parlor. One licks her ice cream; one sucks her ice cream; one bites her ice cream. Which one is married?"
The teacher paused. Then said, "The one who bites her ice cream is married."
"No, the one with the wedding ring is married, but I like the way you think!"
