The top ten things that sound cool when spoken by a giant robot

No it's Leno > Conan > Kimmel > Fallon > Craig > Letterman

Leno is the only of these people who isn't completely awkward for 20+ minutes per show.

I despise Leno. His hair even offends me. I despise his band even more. In fact, I think I hate the guitarist so much it rubs off on Leno. It's hard to describe what boiled my blood about the entire Jay Leno Tonight Show, it just did. Even if he isn't as creepy as Letterman, the extent to which he manages to be a pompous "blue collar" pineappleer annoys me. I'm aware he's as down-to-earth as a celebrity can get, and I read a very impressive bit about him during the writer's strike. But when he's hosting a show... it just makes me want to punt babies into walls of spikes.

I'd give you Kimmel > Letterman, they're pretty even I guess. I hate that Fallon has The Roots as his house band. They are way too good for him and being trapped on his crappy show.
