On Bob's Burgers last night, it was Tina's 13th Birthday. Like any awkward and slightly creepy 13 year old, she wanted to throw a big party for her entire class (disco ball and everything) for the sole purpose of making out with Jimmy Pesto's son. Bob then has to somehow finance the entire charade and decides to speak to his eccentric landlord, Mr. Fishoeder (voiced by Kevin Kline). He gets a second job as a cab driver for a week, giving up sleep and becoming a part time pimp in the process.
Tina's plans for the perfect party are further complicated by the fact that Jimmy Pesto and Bob have some lame rivalry going on. But since, for some reason, Tina's birthday party is more important than anything else that happens in the plot, Bob swallows his pride and tries to negotiate with Pesto only to find out that he has to trade his moustache to get Pesto's son to come to the party.
Bob then gets drunk, invites his transvestite prostitute friends to come to his daughters party, shaves his moustache (just when Tina decides to become a woman and stop nagging her father to fulfil her every wish) and gets even with Jimmy Pesto. Oh and Tina gets her kiss, with a backdrop of rainbows, unicorns, pink hearts and a sleazy cupid.
