30 Rock didn't offer much in terms of plot last night, but after some of its recent episodes, that turned out to be a good thing. Sometimes the show simply tries too hard.

With Mother's Day just around the corner, "The Moms" marked a return to the pleasantly pointless and hilarious zaniness that makes 30 Rock one of TV's funniest shows.

All the moms descended on 30 Rockefeller place, several of which we've memorably seen before. This isn't to say the episode didn't offer new revelations. We now know:

• Liz could be Buzz Aldrin’s son (Buzz quotes? Funny stuff)
• John Lutz's mom looks like (and was played by) John Lutz
• Tracy has no idea what his mom looks like
• Jack is totally a mama's boy and always was
• Verna, Jenna's mom, is complete trailer trash

Okay, the last two items aren't new, but it was great to see Elaine Stritch and Jan Hooks back as these maternal influences. It's amazing Jenna and Jack aren't in therapy.

Jenna's reaction (and ours) to pretty much anything her vile mom says.

To us, the strength of this episode was Tracy, and how he, perhaps more than anyone else, melds the absurdity of 30 Rock with genuine heartfelt moments ... yes, we're serious.

His relationship with his "mom," which evolved somehow into Pete getting him a fake one from an infomercial, somehow made sense when you consider who you're dealing with.

Tracy can be over the top, but amazing to watch when he genuinely believes in his own heart and thought processes. He's like Jenna in that sense, completely in his own world.

Some of the jokes were hit-or-miss, but all in all, 30 Rock got this Mother's Day weekend off to a terrific start with last night's installment, and got itself back on track as well.
