Continuity mistake: This is a flashback episode of Robert's Divorce - they show that Joanne dumped him because she didn't like their life together but in another episode, Ray says that Joanne dumped him for a guy that he arrested.
Super Bowl - S5-E13
Factual error: Ray, Gianni, Robert and Frank are watching a football game when Ray gets the call from Newsday to cover the Friday press conference for the Super Bowl that weekend. There is a 2 week break between the AFC/NFC championship games and the Super Bowl, so there would be no NFL game on TV at the time. There would also be no NFL game on during the afternoon on a weekday.
Other mistake: Marie and Ray's stateroom has a porthole in the back wall, but the hallway outside runs perpendicular to the wall with the porthole in it. This would only be possible if their stateroom was hanging off the side of the ship.
Visible crew/equipment: When Ray is zipping up his pants after Debra lets her parents in the front door, you can see the boom mike directly above Lois' head. (00:06:10)
Continuity mistake: Throughout the show the twins' names changes from Matthew and Gregory to Michael and Jeffrey.
I Love You - S1-E2
Visible crew/equipment: When Robert says "I Love You Debra" the tip of the boom mic can be seen above Raymond. (00:17:20)
Good Girls - S2-E19
Continuity mistake: How is Robert's birthday, which is April 6th, the same day as Amy and Robert's one year Anniversary, when Amy and Robert started dating "a couple weeks before Valentine's Day"?
Revealing mistake: Marie brings a covered cake to Raymond's for Robert's intervention, but it's obvious there is no cake on the plate because her dress is visible through the dome covering the cake plate.
