fallon is shit. for you to put craig ferguson over conan is INSANELY DUMB, and for putting fallon over him you should be slapped repeatedly with supas moms fupa. Conan>all.
Leno is always entertaining, but I gotta give it to Conan because his ad lib stuff is better than the actual written jokes. Fallon and Ferguson aer just dead weight.
Always liked Leno, hate Letterman, find Ferguson boring, Conan is annoying.
don't even get me started on jimmy kimmel
However, I think Fallon might do OK. I always liked him on SNL, mostly because I thought it was hilarious when he and Horatio Sanz broke character all the time. Plus, he was in two of my favorite skits at the time (the Boston white trash one and the stoner internet show one).
