Replacement hosts suck

[Undertoad]

Been watching the replacement hosts while David Letterman recovers from his illness, and boy! do they suck!

Every night there's another one, and every night they come across as nervous, forced, etc. It just goes to show how difficult it really is to be a quality host, and how completely natural and comfortable Letterman is with the camera.

Only two of the replacements I've seen have been good. Elvis Costello was like a natural out there, and his instinct to entertain and his quick wit were obvious. Last night Bill Cosby did his bit, and Cos' quality is that he knows specifically what's funny and can extract his brand of broad humor from almost anyone.
