On the new 'Late Show' (weeknights, 11:35PM ET on CBS), David Letterman showed off his own unique holiday tradition. Once again, Toy expert Shannon Eis appeared on the show, and let Dave try out the season's trendy new playthings. One of the toys: a $400 electric go-kart.
The host jumped into the go-kart and put his foot on the gas. "There's no reverse?" he asked. Oh, that wouldn't be necessary anyway. After all, Dave had a ticket to ride, and he didn't care. He hit the throttle and spun around the stage, nearly colliding with his cameraman -- then rammed the kart directly into a 15-foot-tall Christmas tree, which collapsed, scattering ornaments everywhere.
