I only remember Ozzie because he's a Cardinal (GO CARDS!)

Although Keifer Sutherland has appeared more than once, I thought the one where he was Jack Bauer was very memorable. And we even got a prank call out of it.

Firestar007

Definitely a memorable one with Kiefer playing Jack Bauer. In what other episode did he come in before that one? Can't remember

Grilka

It was the episode where Bart joined the service, but Homer took his place. Keifer played the Drill Sergeant who kept assigning guys to front line infantry.

Firestar007

Yeah I remember now

Hmm, some good ones have been mentioned here. The baseball players were great. I liked Glenn Close too.

I just watched the one with Mark Hamill and he was great.

I'm surprised that no one has mentioned Kelsey Grammer. Or does he even count b/c he's done so many?

Grilka

Maybe Kelsey falls under the same category as the late Phil Hartman, where they've appeared so many times, there really isn't one appearance that stands out.

Firestar007

I love the one with Mark Hamill Love when Homer carries him

Yeah I put Kelsey under the same category as the late Phil Hartman where he's been on some many eps already.

?

I remember when Bret Hart was on an episode. I think it was some kind of recycling one when Mr. Burns and Lisa teamed up temporarily.

Firestar007

Yeah it was the recycling episode.

Lain

Is it possible to mention other characters that have made cameo appearances such as The Archies (where Sideshow Bob runs for Mayor) and Oscar (the episode where Homer becomes Sanitation Commissioner)?

Firestar007

Of course, Kris

I remember Peter Griffin from Family Guy making an appearance on a TOH. It was the one where Homer has a magic hammock that clones, and Peter was in the crowd with all the Homers.

Lain

I always wondered what was up with that And there was the original Homer during the Tracy Ulman days.

Firestar007

Also we've seen Hank Hill from King of the Hill in one episode where he is sitting at a football game.
