NEW YORK (AP) - President Barack Obama and David Letterman were trading compliments and laughs Tuesday night.

Obama appeared on the "Late Show" and Letterman told the president that he's looking good. Obama said Letterman was looking sharp, too.

Letterman replied the president hasn't seen the talk show host "naked." President Obama got an even bigger laugh from the audience when he replied, "We're going to keep it that way."
