I really wish these guys would stop whinging about Leno. What's done is done. Enough already. Conan is highly over-rated. Letterman is nasty. Leno shows professionalism by not shitting all over these guys every chance he gets yet crap that happened well over a decade ago (in Letterman's case) is fodder for his ratings.
He doesn't need to rely on the crutch of tearing down Letterman and Conan every chance he gets in order to get ratings. Sorry, but I just don't find Conan all that funny. I watch Letterman, but just don't find Conan to be what he's cracked up to be.
The Jimmys blow all these old farts out of the water, anyway. Letterman stopped being funny long ago. Jay Leno never was. And Conan is still acting like he's 25, when he was funny, but it doesn't work anymore.
Perhaps It's because I'm now lame, but I'm almost never up late enough to catch late-night TV. Back when I did though, Jay Leno was the equivalent of tapioca pudding. He's kinda OK if you've got no other dessert option, but not nearly as satisfying as almost any other decent show.
