It’s the anniversary of Britta and Troy’s first date. But Troy cares more about his anniversary with Abed because one year ago, they watched Freaky Friday…and they try to do the whole switching places thing but it doesn’t work. Or does it….The next morning, Troy’s acting a little bit Abedy, and Abed is acting a little bit Troyesque. After taking a moment to inspect the goods, they start the day in bizarro world.

When Troy and Abed arrive in the study room, they explain what happened with the whole switcheroo thing, and, like Chevy Chase, nobody cares. In order to switch back, they will need to recreate yesterday, which means finding the lost Freaky Friday DVD.

Britta calls Troy and Abed out on their story by going on her anniversary date with Faux Abed, who’s supposedly Troy. Then, they have “the talk.” About their relationship. Britta finds it easier to talk to Abed about Troy, so it helps that Troy is Abed. Then Troy, as Abed, breaks up with Britta, who is Britta.

Meanwhile, Dean Pelton tricks Jeff into switching bodies, and the results are rather amusing. Faux Troy has a talk with Jeff, who is now real Jeff again? Or is this Dean Pelton pretending to be Jeff? Somehow, Faux Dean Pelton is really Jeff. So there are two Jeffs? But this Faux Pelton must be Jeff because he says, “I’m at Greendale, stuck in the body of a man who could be Gollum.” Plus, Annie is oddly attracted to him.

Jeff, who may or may not be Dean Pelton, tells Faux Troy that Real Troy needs to show Britta that he cares. So Faux Troy finds Faux Abed, and they switch back to their own bodies (checking the goods for authenticity again). Then, the really real Troy tells Britta that he wanted it to work so badly…but they’re better in the friend zone. It’s okay, though. No really. They hug it out and everything.

While everyone was out Freaky Fridaying, Chevy Chase made all of the history banners. And, Dean Pelton says “having Jeffrey inside of me” about twelve times too many. But in the end, everyone is who they are supposed to be, and with who they are supposed to be with. I think.

After gratuitous shots of Britt in black lingerie, Abed convinces Jeff to join everyone on a roadtrip to the Inspector Spacetime convention, or “InspectiCon” for those who choose to leave their action figures hermetically sealed in the original packaging. And by “everyone,” I mean not Chevy Chase.

At the convention, Britta is on a mission to find the only female inspector, Annie tries out a little cosplay, and Jeff wants to leave and go skiing…until he realizes that he bears a striking resemblance to a character on the show, Thoraxis.

One of Abed’s Internet friends, Toby, shows up. This freaks Troy out because the bond between Internet friends is strong and he is afraid that Abed will replace him with Toby. Britt advises Troy to play it cool so that he doesn’t scare Abed off.

Meanwhile, Shirley and Chevy Chase arrive even though nobody wants them there…except for the market researchers who are focus grouping an American version of Inspector Spacetime. Chevy Chase immediately ruins the show by suggesting they cast a tall blonde chick with a tennis racket.

And where’s Annie? Oh, she’s alone in a hotel room and goes a little batty when the room service guy calls her “Mrs. Winger.” She weaves an elaborate fantasy about their perfect marriage, until the room service guy tells her that Mr. Winger is in the lobby chatting up a lady (who has mistaken him for Thoraxis).  Rather than come back down to reality, she plays it out to the end and Jeff ends up with a drink in his pretty face.

Troy goes similarly psycho girlfriend on Abed, and it sends Abed running into the arms of Toby. But there’s something off about Toby. Like most Internet friends, his story doesn’t quite add up. Plus, he’s a walking Wallace & Gromit character. Abed realizes that he needs both Troy and Toby, but Toby’s not interested in sharing Abed with anyone and locks him in a phone booth. This leads to a Troy and Toby showdown, with Toby surrendering quicker than the French, and Troy and Abed rekindling their bromance.

Speaking of bromances, Jeff confronts Annie about the whole “Mrs. Winger” thing. She fesses up that she was upset about being ditched at the convention and maybe was sort of fantasizing that they were married. He lets her down easy, but to make him suffer just a little bit, she forces Jeff to order her an appletini. And that’s when we get treated to Jeff ripping off his shirt. Don’t ask, just enjoy the visual.

Oh! And cameos by Luke Perry and Jennie Garth starring in the American version of Inspector Spacetime. Thank you, Chevy Chase.
