Funny Men: Jon Hamm and John Slattery Battle for 30 Rock Guest Star Supremacy

"Brooklyn Without Limits" may have been Jane Krakowski's Emmy episode -- and it was certainly one of the funniest 30 Rock episodes from a very funny season -- but it was also notable for the appearance of Lincoln pitchman and Emmy nominee, John Slattery. The Mad Men star portrayed Steve Austin (not the wrestler, though if you are blind that's negotiable), a Rhode Island Tea Party wackadoodle running for Congress, and he was so utterly brilliant that it called to mind another Mad Men star who moonlighted on 30 Rock: Jon Hamm. Which employee of Sterling Cooper Draper Pryce acquitted themselves better in Tina Fey's funhouse? Movieline investigates ahead.

· Role

Being a flannel-wearing slavery proponent certainly gave Slattery's Austin an edge in complete absurdity, but it also was sorta one-note. (One hilarious note, but still.) Meanwhile, as Dr. Drew Baird, Hamm has been able to actually develop over the course of 30 Rock's last few seasons: From Liz Lemon's handsome doctor boyfriend ("He looks like a cartoon pilot") to a handless idiot. Both wildly subvert their Mad Men type, but until Slattery gets to destroy a set with his hook-hands, Hamm's the choice.

Advantage: Hamm.

· Relationship with Main Scene Partner

Here's a funny thing about Tina Fey: She has crazy good chemistry with everyone. From Alec Baldwin to Jason Sudeikis to Matt Damon to Hamm, it isn't hard to imagine any number of men falling for her embodiment of Liz Lemon. That said: Everyone has chemistry with Tina Fey! It's decidedly more difficult to warm to Baldwin -- which is why Queen Latifah's appearance earlier this season was dud-ly. That Slattery absolutely killed opposite Baldwin is something that cannot be stated enough. There were times when it even looked like Baldwin didn't even know how to react to Slattery -- not in a character-to-character way, but in reality. It was the stuff dream comedy was made of, kids.

Advantage: Slattery.

· Comedy Chops

From the minute Mad Men began, we always knew John Slattery was funny; not so for Jon Hamm. So it was a great and surprising shock -- one that has certainly dissipated since -- to see Don Draper act so funny on 30 Rock. (Bear in mind, his initial appearances even pre-date his SNL run.) Steve Austin was certainly a different type of funny for Slattery, but he still didn't feel like a total reach.

Advantage: Hamm.

· Willingness to Look Silly

As mentioned, Jon Hamm's 30 Rock character winds up with hooks for hands; Slattery's produces a campaign ad that features him as a newborn, brandishing a shotgun. Watch below, laugh, then consider this a push.

Advantage: Push.

· Intangibles

If you believe the old adage that comedy is harder to play than drama, consider how difficult it must be for an ostensibly intelligent person to play stupid. Very stupid. As such, Hamm's job making Dr. Drew actually work on 30 Rock cannot be discounted. The same goes for Slattery, albeit on a much smaller level. That his Rhode Island/Masshole accent was way better than Julianne Moore's is also of note. Still, the advantage of time allows Hamm to triumph again.

Advantage: Hamm.

WINNER: In a somewhat tight race, it appears Jon Hamm is the winning Mad Men star! (He's honored, I'm sure.) Truth be told, though, we're all winners, since both Hamm and Slattery were beyond hilarious in their sojourns to Rockefeller Center. Here's looking forward to Vincent Kartheiser's appearance next season. Hey, it's either him or Bert Cooper.
