Jimmy KimmelJimmy Kimmel took the stage on 'Jimmy Kimmel Live' dressed up as his sometimes-rival Jay Leno, complete with grey hair and faux chin.

"Hello, hello, my name is Jay Leno and let it here by be known that I'm taking over all the shows in late-night," he quipped, referring to the recent dustup at NBC.

"It's great to be here on ABC," he adds. "You know what ABC stands for? Always Bump Conan."

"Conan O'Brien, today, announced that he is leaving NBC. He released a statement today saying 'I won't participate in the destruction of 'The Tonight Show.'" Fortunately, though, I will," Kimmell says as Leno.
