Dennis and Dee's estranged father, Frank Reynolds, returns to town to reconnect with his kids. They don't want anything to do with him, but Frank likes hanging with Charlie and Mac. Meanwhile, Charlie gets hit by Dennis's car (accidentally, of course) and needs to use a wheelchair. The gang soon discovers that this isn't all that bad.

Driven to distraction by their dad, Dennis and Dee quit Paddy's and decide to go on welfare. Back at the bar, Frank is driving Mac and Charlie crazy. He's also beginning to treat them like sons.
