And here I thought Jay Leno and Jimmy Kimmel were friends.

Many viewers were probably a bit confused last night when they stayed up late to watch Jimmy Kimmel Live right after Nightline. Did they accidentally switch channels to NBC? Did their clocks go back an hour? No - that wasn’t Jay Leno they were seeing. That was actually Kimmel fronting his own show - the entire show - while dressed as his competitor.

“Hello, hello, my name is Jay Leno...and let it hereby be known that I’m taking over all the shows in late night, beginning with this one,” the faux NBC host explained.

“It’s great to be here on ABC. Hey Cleto - You know what ABC stands for?” Kimmel then asked his bandleader. “Always Bump Conan.”

The Leno lookalike then addressed the decision announced by Conan O’Brien earlier in the day. “Anyway, Conan O’Brien today announced that he is leaving NBC. He released a statement today that said I won’t participate in the destruction of The Tonight Show. Fortunately, though, I will.

Wow. Just how much nastier do you think the late-night barbs will get between now and February 12?
