You Ought to Be in Pictures - S5-E28
Deliberate mistake: The movie director tells everyone "ACTION!" Yet Rob stands outside the door and doesn't come in, then he says "uh...action?" Then Rob pokes his head in and asks Leslie "Did you say something?" In "Somebody Has to Play Cleopatra" Rob is the director of the play. He says "Action!" and then Harry (Bob Crane) does not come in on cue several times. Rob also calls Leslie "Liz". (00:15:35 - 00:16:20)
Love Thy Other Neighbor - S5-E29
Other mistake: Laura tells Rob that Jerry is fixing the fence. Then all of a sudden this banging that sounds like an iron hammer and chisel on cement starts up. If Jerry was actually fixing the fence it would have been the whole time, right when Rib got into the kitchen, not right after Laura told Rob that Jerry was working on the fence.
Continuity mistake: Laura is reading the name of Rob's book "Unimportant Life of Robert F. Petrie" yet in "Fifty-Two, Forty-Five or Work" Rob said his name was "Robert Simpson Petrie"
Revealing mistake: Millie (in Rob's dream) tells Jerry (Doc) that "Big Bad Brady is already dead" yet we see that Brady is up there trying to not move, laugh or breathe. He's still alive if his stomach is still going and moving the whole time. Also when he aims his pistol at Rob, he's aiming it at Rob's hat. Not at Rob's arm. Which is where Rob said he got "shot".
