On this Valentine's Day-themed episode, Liz reviews past relationships. Jon Hamm and Bon Jovi guest star.

As the episode gets underway, Liz is without a date, Toofer is set up on a date (with an ... urban woman), Frank is doing his usual Frank stuff, and Lutz is talking to the gang about his girlfriend, who no one believes is real.

But he says that he has the proof on his web site.

Unfortunately, the appearance of Floyd, Dennis, and Drew was only a figment of drugged-out Liz's imagination. Still, we got to see Jason Sudeikis, Dean Winters, and Jon Hamm impersonating the medical assistants at the end (another hallucination by Liz) and that was classic.

In the end, Liz found out that even a crappy Valentine's Day is better than not even having someone to drive you home from a root canal.

Jenna, meanwhile, was on a missing-her-stalker-on-Valentine's-Day kick. She is seriously insane. She's had a stalker for years and years.

She makes even Frank appear normal.
