Life’s good for deliveryman Doug Heffernan, until his newly widowed father-in-law, Arthur, moves in with him and his wife Carrie. Doug is no longer the king of his domain, and instead of having a big screen television in his recently renovated basement, he now has a crazy old man.
Doug's position as the "Funny Guy" is threatened, when IPS' new employee wins over the workforce with his impersonations. Meanwhile, an assistant is hired to work for Carrie, and ends up performing more work than expected.
