Greg's big day is his birthday. Kim wants to take him and the kids to Disneyland, but Jimmy talks Greg into going out and partying like he did when he was single. Greg begins to wonder if he made the right decision after he goes cruising with Jimmy's aging frat boy friends, Chuck, Steve and Gino. While trying -- and failing -- to get into a cliquey club, Greg, Jimmy and company run into Bret Michaels from Poison. Jimmy introduces himself to Bret, and soon everybody is invited to a wild party Bret's having. Greg, out of his element, is surprised to learn that the real Bret Michaels lives the same kind of family life that Greg does, and is merely hosting the party for some of his friends who are in town. At Bret's urging, Greg returns home, realizing that the only place he should be spending his birthday is with his family.

When Greg and Kim learn that Jimmy and Christine aren't throwing a birthday party for Dominic, they plan one themselves. Jimmy intends to start looking for a job to pay Greg back. Greg tries to dissuade Jimmy, who intends to start looking for a job at the studio where Greg works. Greg unwillingly brings Jimmy to the studio for an interview -- where he tries to make Jimmy look unhirable -- but, to Greg's horror, Jimmy lands a position as their security guard anyway. Greg is further horrified to hear that Jimmy spent his first 9-to-5 schmoozing with the head honcho, Gary, whom Greg is afraid to talk to. Greg fears Jimmy will get both of them fired, especially after Jimmy takes it upon himself to invite Gary to Dominic's party. After Greg sees for himself that Gary actually likes Jimmy, Jimmy presses Greg into talking to Gary. But Greg's nervousness makes Gary think he's a deranged stalker. Worse, he gives Gary's allergic kid a peanut cookie that lands him in the emergency room. In the en

Jimmy's best friend, Billy, comes to Los Angeles in hopes of becoming a star. But since Jimmy doesn't have a place of his own for Billy, he instead asks Greg to let his friend pitch a tent in the backyard. Greg, annoyed at having houseguests who have houseguests, makes no secret of the fact that he thinks Billy's dream of acting is a waste of time. Greg later gets jealous after finding out that Jimmy is taking Billy to a hockey game when he had previously offered that extra ticket to Greg. Trying to make up with Greg, Jimmy manages to get a third ticket so the three of them can go, but Greg continues to feel left out when Jimmy and Billy have seats next to each other, and he has to sit alone. Greg feels better after hearing from Jimmy that he's tired of Billy after spending so much time with him. Then both of them are stunned when Billy blows them off after his very first audition lands him a starring role on CBS' The District.

Kim drags Greg along to church against his will. The church's minister, Reverend Green, introduces Greg to Bill, who runs a daddies group where all the church daddies get together and learn how to be better husbands and fathers. Because Kim wants him to, Greg reluctantly joins it and then tricks Jimmy into going with him. When they get to Bill's house, Greg and Jimmy discover the entire daddies group thing is a front -- the guys just sit around, drink beer, watch sports and enjoy some peace away from their wives. That's how they learn to be better husbands and fathers. But guilt eventually overcomes Greg when he is forced to lie to Kim to keep the group's secret safe.

While eating out, Jimmy and Greg run into Billy, who's been sacked from The District and dumped by his girlfriend, and now works at a restaurant as a birthday-wishing pirate. Until he gets sacked from that job too. When Kim receives an estimate on a bathroom remodel that looks high, Billy -- who used to do bathrooms -- confirms to her that it is high. Jimmy tries to talk Greg into letting Billy do the bathroom for them, but Greg doesn't need the pep talk after Billy says he'll do the job for half the price. Kim brings home a friend from pottery class, Rosanna, who takes an immediate liking to Billy. Billy and Rosanna go out on a date that makes him think they're on the fast track to a relationship -- until Rosanna tells him that she's decided to get back together with a former boyfriend. The news crushes Billy so much that he can't work and, hence, can't finish the bathroom. With the pipes turned off and no running water, Greg and Kim are forced to share Jimmy's and Christine's bathroo

The Warners and the Hughes invite the neighbors, Rob and Wendy, and their kids over. Greg decides to join a gym after seeing Rob give rocket ship rides to Sam, because he's too exhausted to give them to Sam himself. But Greg has no idea what to do at the gym and contemplates hiring a personal trainer, which Jimmy thinks is a waste of money. So he volunteers to personally train Greg himself. Christine, meanwhile, thinks about taking Logan out of day care because she's bored. Kim instead convinces Christine to go down to a temp agency and get a part-time job that she's qualified for -- passing out teeny-weeny samples at the supermarket. Jimmy loves Christine's new job -- especially the free lunch part -- but Christine hates it so much she quits, and tries her luck again at the temp. This time she gets an even worse job, and quits it too. Jimmy overworks Greg so much that he's ready to quit working out himself, until Jimmy confesses that he's only been ""helping"" Greg to avoid taking care

Greg goes through an old jacket and finds a wedding invitation Kim asked him to give to her friend, Julie Grimes, years ago. Make that ex-friend, since Kim cut Julie off for not showing up at her wedding. Greg worries Kim will think he forgot to deliver it on purpose as he never liked Julie or found her funny, which Kim, Christine -- and Julie -- all did. Christine says he should just show Kim the invitation to clear Julie's name, but he throws it away. It's only after he learns that Julie moved to LA to become a comedienne and Kim sadly feels she has no friends anymore because of what Julie did that Greg decides to pay Miss Grimes a visit to clear her name to her instead. Julie, who was crushed that Kim never invited her, is relieved that she in fact did, and agrees to patch things up -- starting with an invitation to her own wedding that she wants Greg to deliver. But Julie is as unfunny as ever, spouting one catchphrase after another, that he throws her invitation away too. Meanwhil

Greg announces that he may soon become Executive Director of Business Affairs, instead of what he is now... Executive Manager of Business Affairs. Since the new position is between him and his co-worker, Stuart, Jimmy recommends he suck up to his boss to ensure he gets it. Though initially skeptical, Greg has a chance to follow that advice when he goes to see Jimmy play at the studio's softball game, and bumps into his boss, Mr. Savitsky. Jimmy hits a home run and wins the game for his team. Then Greg gets the promotion. Greg is annoyed when Jimmy brags that his home run clinched it for him. Fearing Jimmy might be right, Greg asks Savitsky point blank if he got promoted over Stuart because he works harder. Savitsky tells him he did, but when Greg brings up Jimmy's home run afterwards, Savitsky remembers that it was because of the home run after all. Humiliated, Greg lies to Jimmy that Savitsky told him it wasn't. Jimmy pretends to be soundly defeated before revealing that Savitsky alre
