Zach Quinto on Letterman, Michael J. Fox on Kimmel, Kate Walsh on Ellen
So, Zachary Quinto's doing "Letterman" the day after the "Heroes" finale, probably to promote "Star Trek" though, no? Michael J. Fox -- whom I hope you're watching on "Rescue Me" right now -- is doing "Kimmel." Who else? Who else do you care about on this list? I'm going to watch Handler on "Leno" because she's hilarious and will probably make some crude health/hospital related jokes at Jay's expense...
"Late Show with David Letterman": Zachary Quinto
"The Tonight Show with Jay Leno": Chelsea Handler
"Late Late Show with Craig Ferguson": Stana Katic
"Late Night with Jimmy Fallon": Jason Segel (repeat)
"Last Call with Carson Daly": Sprague Grayden (repeat)
"Jimmy Kimmel Live": Michael J. Fox, DWTS eliminee
"Chelsea Lately": Nadine Velazquez
"The View": Emily Deschanel, Kim Kardashian
"Live with Regis and Kelly": Matthew Fox, Jill Hennessy
"The Ellen Degeneres Show": Kate Walsh
"The Bonnie Hunt Show": Carson Daly, Phil Keoghan

I like your picks! I used to have "Chelsea Lately" taping on my DVR but Comcast can't figure out what is a rerun or it records the same episode 6 times in a row. This is good that I check here every day to see when a new one is on and who's on it.
Glad to know that the lovely Stana Katic is getting some press...everyone is watching "Castle" right?!
And of course Zach Quinto is promoting "Star Trek". Surely you don't think that he'd be promoting "Heroes" after last night's debacle, do you?!
Please include what day these appearances are taking place on.
DR. ROCK, THE APPEARANCES ARE TAKING PLACE TODAY!!!!!! WHATEVER DAY THE POST IS POSTED.
