Euan's quest to find a steady girlfriend lands him Ginger, an artist who Mike believes is taking Euan for all he's worth. Meanwhile, Liz proves to Mike that her revealing clothing makes him uncomfortable.

When Liz and her wild, flirty friend stay at the apartment for the weekend, Mike hopes for a ménage à trois. Euan, who has resolved to remain celibate with his current girlfriend, serves as Mike's mentor.

Mike's strange parents visit, allowing Mike to finally bond with his erstwhile, emotionally distant father. Unfortunately, Euan finds Mr. Platt in a compromising position with another woman.

Sick of living with Euan, Mike decides to stay at Lauren's for a while. As revenge, Eaun invites Chau to live in Mike's room. The unlikely duo get along well, until Chau's behavior gets out of hand.

After Mike and Euan point out that his ""posse"" is a bunch of yes-men, Status Quo fires them and invites his neighbors to hang with him. Unfortunately, he treats Euan more like a slave than a friend.

Mike and Chau start going to a gym where a lot of nude men hang out; Euan dates Liz's deaf friend, who turns out to be less friendly than anyone realizes.

Mike tells Euan to stay away from an attractive visiting friend, explaining that she is his ""backup girl,"" should things not work out with Liz. Meanwhile, Chau pulls out all the stops to try to win a contest for a big-screen TV.

Mike and Chau mock Euan because he has a foreskin. This prompts Euan to consult a urologist, Dr. Barry Wasserman, who has a bizarre sense of penis humor, for circumcision.

Mike feels that his relationship with Liz has gotten stale, so he decides it's time to break up and is not prepared when she beats him to the punch, however the break-up sex is so good that Mike does everything in his power to string the relationship along. When Euan meets a woman who is even wilder in bed than he is, he soon learns that even he has limits. Chau rallies to save a canceled TV series.

Euan and Status Quo meet a gorgeous woman in a bar and compete for her attention. When they realize that she has a twin, their competition escalates to see who can bed them both. Meanwhile, Mike realizes that the only way he can earn extra money to purchase an extravagant birthday gift for Liz is to bet on cockfights with Chau.

Mike impresses the guys when he leaves the bar with the new building tenant, Carmen Electra, however, back at her apartment, Mike's new diet causes him to clog her toilet. Undetected by Carmen, Mike enlists the help of his good friends Euan and Chau to help clear the blockage.

In a competition to prove whether it's simply Euan's English intonation that attracts all the women, Mike and Euan switch accents. Meanwhile, Chau dates a homeless woman who is not entirely sane.
