Dad: Son, come in here, we need to talk.

Son: What's up, Dad?

Dad: There's a scratch down the side of the car. Did you do it?

Son: I don't believe, if I understand the definition of "scratch the car", that I can say, truthfully, that I scratched the car.

Dad: Well, it wasn't there yesterday, and you drove the car last night, and no one else has driven it since. How can you explain the scratch?

Son: Well, as I've said before, I have no recollection of scratching the car. While it is true that I did take the car out last night, I did not scratch it.

Dad: But your sister, Monica, has told me she saw you back the car against the mailbox at the end of the driveway, heard a loud scraping sound, saw you get out to examine the car, and then drive away. So again I'll ask you, yes or no, did you scratch the car?

Son: Oh, you mean you think you have evidence to prove I scratched it. Well, you see, I understood you to mean did "I" scratch the car. I stand by my earlier statement, that I did not scratch the car.

Dad: Are you trying to tell me you didn't drive the car into the mailbox?

Son: Well, you see sir, I was trying to drive the car into the street. I mishandled the steering of the car, and it resulted in direct contact with the mailbox, though that was clearly not my intent.

Dad: So you are then saying that you did hit the mailbox?

Son: No sir, that's not my statement. I'll refer you back to my original statement that I did not scratch the car.

Dad: But the car did hit the mailbox, and the car did get scratched as a result of this contact?

Son: Well, yes, I suppose you could look at it that way.

Dad: So you lied to me when you said you did not scratch the car?

Son: No. No, that is not correct. Your question was "Did I scratch the car?" From a strict legal definition, as I understood the meaning of that sentence, I did not scratch the car ... the mailbox did...I was merely present when the scratching occurred. So my answer of "No" when you asked "Did I scratch the car" was legally correct, although I did not volunteer information.

Dad: Where did you learn to talk like a complete idiot?

Son: From the President of the United States.
