Jay Leno Jay Leno

Jay Leno signed off his self-titled talk show for the last time Tuesday, joking that NBC was allowing him to end the network's failed prime-time experiment after only five months "for good behavior."

"We were on the air five months," he said in his final Jay Leno Show monologue. "It seems like just yesterday I was telling NBC, 'This is not going to work.'"

Besides scheduled final guests Bob Costas and Ashton Kutcher, Leno welcomed Donald Trump via satellite. The Apprentice star opted against a sentimental farewell and told the always-jovial comic, "You're fired!"

On March 1, Leno will return to The Tonight Show, which he hosted for 17 years before being replaced by Conan O'Brien for just seven months.

In a TVGuide.com poll, 69 percent of users said they used to watch Leno, but will not watch anymore after what happened to O'Brien. Only 15 percent of voters say they will continue to watch the late night host in his old slot.
