Following Jimmy's advice, Greg spots a young, attractive couple with a kid of their own, and gets Sam to play with theirs instead. Jimmy's worst nightmare comes true when he sees Christine let Logan play with the old couple's child anyway. Greg and Kim get to go out with the young, attractive couple, John and Rebecca. Greg naturally thinks he got the better deal -- until he and Kim learn the hard way that their couple are violent lunatics prone to road rage.

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.

At Bret's urging, Greg returns home, realizing that the only place he should be spending his birthday is with his family.

Christine and Kim plan a trip to their parents' house. Jimmy agrees to go to please his wife, but Greg doesn't care to go that far to please Kim, and weasels his way out of it.
