I KNOW! What's with that. I can't believe that Ben Stein unleashed this ass upon the world.

I thought he was somewhat amusing on Win Ben Stein's Money.
An interesting question is why has he lasted so long on ABC?
Chevy Chase's talk show was funnier at times than Kimmel.
Does he have a Scott Boras-type super agent? Is Kimmel's contract so lucrative that it makes financial sense to keep the show running rather than to buy him out?

I've never seen Jimmy Kimmel's talk show, but I thought he was pretty funny when he used to be on KROQ, as well as the Man Show. Perhaps he's funnier when he has someone else to riff off of?

Never watched a full episode of Kimmel's Abc show. Man Show was funny from time to time as is Crank Yankers.
He was usually really funny on KROQ, but all he really did was the sports report, fawn over Mike Piazza, and be a supporting role so really funny was only required like once an hour, if even that much.
As for how he is now the big name funny star, I have no idea, there are many 'funny' people I'd pick over him.

Tony may have hit it on the head: he's best when he's riffin' off someone else.
Kimmell's best as a sidekick/co-host. I thought he was a frickin' comic genious when he was on Win Ben Stein's Money, and was an awsome force on The Man Show.

What little I've seen of his schtick since then has been less than impressive.
Maybe it's just the Peter Principle in action: He has finally risen to his level of incompetence.

Too bad, really. He's busting many a gut in the past.

He's
not
fucking
funny!

i'm sure you will agree Casca, Jimmy Kimmel is to comedy what Vinnie Testaverde is to football.

Did ya see Vinnie lined up behind the fucking tackle tonight?

Gawd dammit, no, but I believe you! I avert my gaze when he's prepared to handle the ball. It's gotta be the name, he's NEVER had any talent.
