David Letterman opened his final Late Show on Wednesday with a light nod to politics, with former President Gerald Ford informing the viewers, "Our long national nightmare is over."
Ford was followed by four of the country's five living presidents -- George H.W. Bush, Bill Clinton, George W. Bush and Barack Obama -- repeating the line, with Obama adding the punchline.
"Our long national nightmare is over -- Letterman is retiring," Obama says, drawing Letterman on-camera.
"You're just kidding, right?" Letterman asks Obama, only to get a shrug.
Mashable posted a gif of Obama's interaction with Letterman:
