Three's Company (1977)

Strange Bedfellows - S2-E4

Continuity mistake: When Mr. Roper tries to explain to the girls and his wife what he was doing in Jack's bedroom, watch over Mr. Roper's left shoulder on the shelf. The number of yellow cans on the shelf keep alternating between one and two cans throughout several minutes. In addition, also notice the suitcase on the floor under the shelf as well. Whenever one yellow can is shown, the suitcase is by itself and whenever two yellow cans are shown, there is a square silver bag in front of the suitcase.

Ralph Furley: Ohhhh, I'm through with women.
Jack Tripper: Aww.
Ralph Furley: Don't you get any ideas.

Trivia: Once the first season with Terri started, Cindy no longer had "Snow" mentioned as her last name for the remainder of the episodes she was in (possibly due to the fact that this was the first season that started without Suzanne Somers completely and the producers wanted to retire the "Snow" surname altogether).

Cyrano de Tripper - S2-E8

Question: In this episode, Chrissy's Date Michael asks her (while eating a salad) "How did you introduce the dressing?" Chrissy responds, "I just said salad meet the dressing, dressing meet the salad." Although the response made for a very funny scene, my question is what did Michael actually mean by "introduce the dressing"?
