Marital bliss turns into business, as the gang experiences the emotional and economic hardships of divorce.

The gang attempts to find adventure on the sea after they purchase their 'new' boat.

Rejected from a pool club, Mac and Charlie set out fix an abandoned pool to help cope with the Philly heat wave. Meanwhile, Dennis and Dee go about dealing with the heat in a different way.

Mac's mother is left homeless after she burns down her house, which leaves Charlie and Mac with no choice but to make new living arrangements; when Dee feels under the weather, Frank tries to muster his paternal instincts to care for her.

A blast from the past prompts the guys to expand membership, and Dee to re-consider her future.

Motivated by the drama teacher who inspired her, Dee takes a job as a substitute teacher, and exposes her students to the culture of Paddy's with a field trip to see the Gang's take on the Lethal Weapon series: Lethal Weapon 5.

Keeping the basement rodent-free drives Charlie to the brink. The gang throws Charlie a surprise party.

En route to Atlantic City for a charity event, Mac, Frank and Dee get lost. Meanwhile, Dennis and Charlie hitch a ride to town.

After years of being mistreated by Frank during the holiday season, Dennis and Dee decide to teach him a lesson. Meanwhile, Mac and Charlie reflect on their childhood Christmases, and realize that they were not as joyous and wonderful as they remembered.
