An audience member claims to know Dave's ex-wife, who apparently now lives in Florida; the show is again interrupted by radio transmissions from Lt. Len Easton of the California Highway Patrol; Mike McIntee and Harold Larkin play "Can Two Guys and Their Dead Friend In An Office Chair Hail a Cab?"; Don Rickles plugs his DVD Mr. Warmth and throws a few zingers at Dave and fellow guest Denzel Washington.
