Season Summary
Dennis and Dee's parents are featured heavily this season. First, their dad Frank blackmails his way into the Gang and moves in with. Then Mac bangs Dee and Dennis' mom. Then finally, Dennis and Dee discover that Frank isn't their real dad - instead, their mom had an affair with philanthropist Bruce Mathis.

Meanwhile, the Gang ups its efforts on the scheming front: first trying to get their neighbor to leave, then attempting to extort welfare from the state. When that doesn't work, they attempt to rig a fight club, exploit a water stain of the Virgin Mary in the Paddy's office and later extort bribes in exchange for running for office.

Finally, the Gang converts Paddy's Pub into yet another highly successful specialty bar: an unregulated bar that caters to drug abusers and gamblers.
