Michael Keaton Talks 'Home Alone' Childhood on 'Late Show' (VIDEO)

Being the youngest child of seven has its perils, as Michael Keaton can attest. On the 'Late Show' (weeknights, 11:35PM ET on CBS), he told David Letterman about the time his family claimed he "fell" out of the car.

"We're driving out ... and at some point the door -- I'm going to do air quotes -- 'dislodged.' I'm out -- boom!" said Keaton. "I'm rolling around like in gravel. I looked like I'd been hit by shrapnel."

Here's where kind relatives would pick you up and rescue you from the middle of the road. Not for this little lad.
