He's suspended from the hospital for that. Sharon volunteers to read to children at the hospital and Pete becomes a volunteer fireman.

The guys at the firehouse make Pete believe that Marty has a thing for him. Pete, Berg and Sharon decide to hang out at O'Malley's, their old college hangout, just like old times since Johnny is having his bachelor party but Johnny shows up anyway and Berg gets mad at him for ruining their evening and punches Johnny right in the face.

In hopes of getting off probation at the hospital Berg lends his apartment to his superior so she can take a nap but she has an affair instead.

Berg lands in a very tight spot when Irene takes their little affair a tad too far; Sharon refuses to get dirty with Johnny until he cleans up the new brownstone; and Ash begins to fall apart after her breakup with Nomar.

Germ feeds Sharon a batch of bad advice about how to get Johnny to fix the home in a more timely manner. Meanwhile, Pete has Marti burning mad when he bugs her about their romance during a rescue.

Pete, Berg and Johnny try to get into a club but end up drinking beer outside a convenience store, after Jonny complains about the price of the beer in there. When they return later to the club with Germ none of them are allowed in, except for Germ. They then go back to to the convenience store but end up getting arrested for drinking in the street. Sharon finds out that Johnny doesn't wear his wedding ring and goes out with Ashley to the club to try and help Ashley find a man, and for Sharon to find Jonny so she can kill him. But they end up having a great time and get piles of phone numbers from single guys.

A near death experience with a runaway fire truck has Pete reevaluating his life--and his loopy love affair with Ashley. Meanwhile, Berg seeks out an old flame to help get over Irene, but finds that she's even crazier than his beloved "cat lady."
