Since Buddy's wife has been away, Buddy has been sleeping at the office and not telling anyone. When Rob finds out, he insists that Buddy come stay with him and his family...but Sally insists that being that close might strain the friendship. But Buddy and Rob think things will be fine...and they don't anticipate what does happen. Yes, Buddy is a nut to live with and it's hard to imagine how his wife, let alone the Petries, can live with that! The problem is that Rob is loathe to tell him to leave...but Laura insists that Buddy must go, otherwise they'll lose their minds.
This is a good episode that covers much of the same ground as an earlier episode...the one where Buddy's dog stays with the Petries. Well worth seeing.
