Howard Stern made his final appearance on the "The Late Show With David Letterman" on Monday night and the two bickered like old spouses over everything from Letterman's retirement plans to a cancelled dinner that rubbed the radio talk show host the wrong way.

And in a moment that truly seemed to catch Letterman off-guard, Stern grabbed the host by his face and repeatedly tried to kiss him on the lips.
"Kiss me!" Stern demanded as Letterman pulled away, turning red. "Kiss me now!"
Stern, a longtime Letterman guest from when "Late Night with David Letterman" was on NBC, also presented a watercolor painting he made for the host's wife.
The two were later joined by comedy legend Don Rickles:
Letterman's final show airs on May 20.
