VIDEO: Peyton Manning and David Letterman throw passes into New York City cabs

Denver Broncos quarterback Peyton Manning appeared on the "Late Show with David Letterman" Monday night and Peyton and Dave took to the streets of New York City to have a little fun.

The two took part in a version of the defunct NFL quarterback challenge, although with a decidedly New York twist: cabs. Check it out as Manning and Letterman go toe-to-toe to see who owns the better arm (note: It's Peyton).
