Plot hole: In the episode "That's my Boy" when they bring Richie home from the hospital, Rob and Laura are living in the house they have for every show. However, in the episode "Where did I come from" when Laura went in to labor, they lived in a different house. They couldn't have moved while Laura was in the hospital.

Continuity: The buildings seen from the window of Rob's office change in different episodes.

Other: When Rob is dancing with Laura and is supposed to step on her foot, his foot lands so far away from hers, it doesn't even appear that he stepped on it.

Plot hole: In this episode Sally asks Rob if he has a brother, Rob says "Yes, but he is married." However his brother Stacy becomes engaged later in the series, in episodes "Stacy Petrie Part 1 and 2."

Continuity: When Laura tries to read the phone number that Rob scratched out, Rob gives her the number as "New Rochelle 69970," which happens to be the Petrie's own phone number, as noted in other episodes. Submitted by GreyWolf

Other: The clerical garb that Father Joe wears to his dinner date at the Petries' is more typical of Protestant clergymen than Catholic priests. A Catholic priest's shirt would not have a white circular collar. Rather it would have a black stand-up collar with a small strip of white cloth inserted in the front.

Factual error: In the scene Laura and Sally are about to go to the bedroom, Buddy and Rob are going to sleep in the living room of the haunted cabin. Rob and Laura tell Buddy and Sally things like how he steals the pillow and he takes all the covers at home. However at home, they sleep in twin beds so they shouldn't know such things. This is true. However, they do have a son. They had to share a bed at least once in their marriage.

Continuity: When Sally lets Burt into her apartment, her hand is on her forehead and then all of a sudden it's down by her side.

Factual error: When Rob climbs up the elevator shaft, he comments on how greasy it is, and when he jumps back into the elevator, he wipes his hands on his shirt but not a bit of grease shows on his clean white shirt.

Continuity: When Laura puts the ice cream in the freezer, the freezer is full, however when Millie brings over the ice they are able to put it in the nearly empty freezer.

Continuity: In some of the courtroom scenes you can see feathers flying around, before Rob spills feathers all over the courtroom.

Other: When Rob dials the radio station, he dials the phone number and then looks it up in the phone book. He covers for himself, and then has a hard time keeping a straight face afterwards.

Continuity: In the first scene, when Laura tells Millie she spent the whole day in the bathtub and Millie says "In a bathtub" Millie moves from sitting on a chair to sitting on the couch next to Laura in a flash.

Revealing: When Rob is talking on the radio, and says something along the lines of WOFF the station with (then a long pause while he plays a car sound) drive. The On the Air sign goes off before he says drive. He was still on the air.

Plot hole: Sally Rogers appears on the Stevie Parsons show which is a late night talk show, the next morning she receives letters from as far away as Hawaii... the US mail isn't that fast.

Other: Rob, Sally and Buddy are surprised that Alan has a Yacht, however in the episode "The Ballad of Mary Lou" they spent the day on it.
