Grandpa was driving his Granddaughter to school one day, and tooted the horn slightly while making a right hand turn.

He looked over and his Granddaughter was just looking at him.

What, he said, It was an accident, give me a break.

I know it was an accident said the Granddaughter.

Okay smartypants, how do you know it was an accident, you can't drive a car.

Because you didn't yell 'Idiot' after you tooted the horn, the Granddaughter said.
