David Letterman closed his 33-year late-night TV career Wednesday with a star-studded, emotional episode of “Late Show” that featured Jerry Seinfeld, Chris Rock, Tina Fey and a musical performance by the Foo Fighters.

The episode opened with a video clip from former Gerald Ford’s inaugural address: “Our long national nightmare is over,” Ford said. George Bush, Bill Clinton, George W. Bush and President Obama followed in pre-taped appearances to repeat Ford’s statement.

“Our long national nightmare is over – Letterman is retiring,” President Obama said. Letterman appeared next to him. “You’re just kidding, right?” Letterman said.

As to what he plans to do now that he's retired? " I hope to become the new face of Scientology,” Letterman quipped.
