Continuity: After Jack brings the puppy over to the girls, the box he brought the puppy in was placed on the table behind their couch. At one point, it is knocked over, and you can see it falling down to the floor (past Janet). In the next shot, it's back on the table, and none of the characters were in a position to pick it up to place it back there.

Continuity: When Janet and Mrs. Roper are found nude behind the bushes, Larry leaves to get towels. However, the yellow towel suddenly appears briefly on screen several seconds before Larry returns.

Continuity: When Jack is eating cake and Chrissy is under the table her the sleeve of her right arm is down. When Jack and Chrissy exit the kitchen into the living room, both of her sleeves are down.

Continuity: Larry gives Cindy and Janet gifts to thank them for letting him live with them, so Janet gives him a kiss. However, three seasons later in the episode "Friends and Lovers," Janet kisses Larry at her wedding to which Larry says "Janet, that's the first time you've ever kissed me."

Continuity: In the scene where Terry puts on the gag glasses, notice how the black circles under her eyes get larger after the shot changes.

Continuity: In the scene where Terri admits to Jack that she mistook his cooking lessons for lovemaking lessons, look at Terri's bangs. They go from on her forehead to brushed back then back to on her forehead then back to being brushed back.

Revealing: In the scene where Jack and Janet are sitting on the sofa with the doctor, Janet offers the doctor some nuts from a bowl. Then take a look at Janet's face. She begins to laugh so she lowers her head and the camera immediately shoots over to Jack who realizes the goof and adlibs something to give Janet time to get into character again.

Continuity: This is such an obvious mistake. In the scene where Jack, Janet and Terri are on the air for the cooking show, Janet holds up the silver bowl but there is no parsley in it. Then in the next shot the bowl is full of parsley. How is it possible that it got filled up in a matter of two seconds.

Visible crew/equipment: Notice the scene when Terry comes out of the kitchen. As the kitchen door begins swinging shut, a mysterious hand (which belongs to a crew member) suddenly appears from offstage to keep the door closed.
