Older Women - S6-E9
Visible crew/equipment: Someone appears behind the kitchen door, when Ray goes, "and I can see how that can make you all... Man-hatey...", and hangs around behind the door for several seconds. (00:15:55)
Continuity mistake: After their engagement in 2-25 "The Wedding", Debra introduces Ray to her priest Fr Hubley but in this flashback episode "The First Time" Marie brings Fr Hubley to Debra's apartment to meet her. The priest mentions that "he's known the Barones for quite some time."
It's Supposed to Be Fun - S6-E8
Other mistake: After Geoffrey is fouled, he takes his free throws on the wrong end of the court.
Continuity mistake: In this episode, while Ray is telling Marie her faults, he has an almost empty glass. In the next shot, his glass has been topped-up slightly without him or anyone else doing so.
The Kicker - S6-E11
Revealing mistake: During the scene after Robert breaks the window with the football, if you look close at the broken window, you can tell that it is some sort of thin material and not glass. Around the break the "glass" is flapping in the breeze like paper. (00:12:20)
The Kicker - S6-E11
Visible crew/equipment: After Robert throws The Ball through the window, if you look between Ray and the door frame, you can see the arm and leg of the crew member that actually threw The Ball through the window. (00:12:15)
