Last night's episode of "Community" featured a very special guest star in "American Idol" runner-up Katharine McPhee -- but what would we put on her report card? We grade "Basic Genealogy" after the jump.

People probably have lots of reasons not to visit Florida. And when I say "people," I mean "people other than me," because hello, Disney World. But on last night's episode of "The Colbert Report," Stephen addressed the latest reason to avoid the state: monkey on the lam! See it above; the rest of last night's late-night highlights are after the jump.

There's no excuse for you not to know about Jerry Seinfeld's new unscripted TV show, "The Marriage Ref": he talked it up last week on "The Late Show," he was on "Live with Regis and Kelly" this morning, and last night, he stopped by "The Daily Show." See the interview above; the rest of last night's late-night highlights are after the jump.

David Letterman is a man of many skills, including tremendous grocery-bagging speed. Or so he thinks. On last night's "Late Show," he faced off against the nation's defending grocery-bagging champion, and nearly tied...with only minor cheating. See it above, and enjoy the rest of last night's late-night highlights after the jump.

These days, Chris Parnell should be best known for voicing Cyril on "Archer." (He probably is best known for voicing the Helping Hand in the Hamburger Helper ads). But just a few short years ago, he made viral-video history opposite Andy Samberg in the deathless "SNL" Digital Short "Lazy Sunday" -- and last night on "Late Night with Jimmy Fallon," he revisited past glory by performing the song live. Watch it above, and hit "continue reading" for the rest of last night's late-night highlights.

There's nothing not to like about Adam Scott and Rob Lowe. In fact, there is a whole lot about both of them to enjoy -- and that's why they are set to appear at the end of the season on "Parks and Recreation" with Scott playing Leslie's love interest and staying on full-time next season. Scott comes to "P&R" from "Party Down," while Lowe departs the drama "Brothers and Sisters." More after the jump.

This weekend's episode of "Saturday Night Live" starred Zach Galifianakis -- and if we could offer a critique, it's that it could have been a lot more Galifianakis-y. Watch the full episode, above, and then let's talk about it after the jump.

Last night's episode of "Community" involved a love connection, a sporting face-off, and a hilarious mispronunciation of the word "bagel." We grade the proceedings after the jump.

"The Tonight Show" had an interview last night with a guy who doesn't know how to let go of the career he loves. You see, this is a guy who's walked away from his passion, only to return to it a few months later. People say he's washed up, but he defies the odds and keeps trotting out to go to work whenever he's needed by his employers. Some people love the guy, others loathe him, but one thing's for sure: Matthew McConaughey was really pumped to be sitting next to Brett Favre during the above interview.

Oh, you thought I was talking about Jay Leno?

The arrival of a baby on a sitcom is a joyous occasion in sitcoms, just as it is in life, and last night's special two-part episode of "The Office" was no exception. But on sitcoms -- again, as in life -- the introduction of babies is something that's been happening for decades, so it's only natural that some story elements would keep coming around. After the jump, we take note of which sitcom-baby clichés were present in last night's episodes -- and a few the producers of "The Office" elected not to include.
