Pete enlists the help of a TV love guru to help Berg and Ashley when Berg calls Ashley to tell her that he thinks they shouldn't see each other anymore. She doesn't take very well and breaks down and cries. And for Sharon and Johnny because Sharon is jealous of Johnny's friend Sean when she finds that Sean is a woman.

Sharon and Johnny fight over wedding plans, Berg and Ashley also fight and Pete runs into a crazy ex-girlfriend.

A mad scientist switches Pete's brain with Ashley's brain and Berg's brain with Sharon's brain and the only who can help them is Johnny.

Sharon tries to reunite Berg and Ashley with the help of video monitors wired to watch the tenants in the building. But it looks like they may not be able to use the cool new tool to save Pete from Irene and her crazy scheme to enshrine him.

Sharon stoops to an all-time low when she eyes her dream dress at a wedding-gown sale. Meanwhile, Ashley tries to fix her own sink after insulting Johnny for his know-how in the "simpler" things in life.

Irene throws Sharon and Johnny a wedding on the roof after Sharon cancels some of the plans, Pete and Marti go off to fireman boot camp and Berg and Irene hook-up.

Berg and Irene race to bury any proof of their fling, while Johnny gives Sharon a post-wedding shock and Pete realizes that, for a firefighter, Marti is a cold, cold girlfriend.

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.

Irene's deal with the Devil gets Pete a spare head, while Berg falls apart (literally) and Sharon one-ups Johnny in the "man" department. But when they try to reverse the curse, things go from bad to worse. And then to "The Twilight Zone."

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.

Berg decides to keep hiding his secret fling with Irene after she blows him off for a last-minute dinner date with Pete. And at the next table over, Johnny blows his lid because Sharon has been spending too much time with Ashley.

Ashley's leaky plumbing has Berg in search of sleep, Pete in hot water with Irene, and Johnny in talks with Sharon to maybe have a baby.
