The Logical Levels of Interpretation
The Schoolteacher asked her class, “a farmer sees three crows on his field, and shoots one of them, how many are left?”.
“None!” exclaims little Johnny, “because the others would fly away as soon as they heard the gunshot”.
“Well, that's true.” says the teacher “I was looking for the answer two but I like the way you're thinking.”.
“I have a question for you Miss” says Johnny. “If three women are eating ice cream, one is biting her ice cream, one is licking her ice cream, and one is sucking her ice cream, which one is married?”.
The teacher blushes slightly and finally utters “the one sucking her ice cream?”.
“No”, says Johnny. “It's the one with the wedding ring. But I like the way you're thinking.”.
