Mark solicits his cousin, Johnny Drama, and friend, Billy Leonard, to take Paul out for a weekend of physical activity when he sees that Paul is putting on a few extra pounds. Back home, Alma solicits the help of Kari and Mackenzie to help clean out her garage. In the search, they stumble across some of Mark and Donnie's most treasured (and embarrassing) childhood memorabilia.

Donnie and Mark decide to play a practical joke on big brother Paul by telling him that they want to create a Wahlburgers jingle. They go even further by recruiting the help of their friend Joey McIntyre (New Kids on the Block.) Never one to miss an opportunity, when their close family friend (and favorite "cousin") Johnny Drama hears about the possible jingle, he also wants in on the writing process. As the gag gains momentum, Paul, the control freak, is overwhelmed by the triple team. While her sons are busy playing tricks on each other, Alma, the shopaholic, is stumped as she tries to find the perfect gift for Donnie's new girlfriend, Jenny McCarthy.
