With President Barack Obama
The 44th president during a Letterman appearance in September 2012. "How much do you weigh?" asked Letterman. "About 180," said Obama. "180 looks good on you," said Letterman. "That's just about where I am and I don't look so good at 180." "You look sharp," replied Obama. "You haven't seen me naked," said Letterman. Obama's rejoinder: "We're gonna keep it that way."
