Mork is talking to the Fonz on the couch, in one part Mork's back is further away from the back of the couch then the next shot, he is leaning more back.
Before the flashback (Fonzie / Happy Days) there is a television on the wicker basket (acting as a coffee table). After the flashback it's gone.
Right after Mindy notices that Mork is not a priest, Mork puts his right hand out then his right hand is closer to his body, then the next shot of Mork, his right hand is touching his left hand.
At 7:25,when Mindy is setting Mork's food down,you can see the shadow of the camera moving behind her on the wall.
