Martin had just received his brand new driver's license. The family troops out to the driveway, and climbs in the car, where he is going to take them for a ride for the first time. Dad immediately heads for the back seat, directly behind the newly minted driver.

"I'll bet you're back there to get a change of scenery after all those months of sitting in the front passenger seat teaching me how to drive," says the beaming boy to his father.

"Nope," comes dad's reply, "I'm gonna sit here and kick the back of your seat as you drive, just like you've been doing to me all these years."
