 * Crowning Moment of Heartwarming: Several times in the episode Secret Admirer.
 * Fan-Preferred Couple: Many fans over the years have expressed disappointment that Jack and Janet didn't get together in the end.
 * Idiot Plot: See What an Idiot! below, and also its tendency to make plots based off stuff from the Comedy of Errors.
 * Recycled Script: An early episode had the roommates trying to hide a recently adopted pet from Mr. Roper. Towards the end of the series' run, a similar plot (with a different animal, Mr. Furley and Terri) was used. John Ritter himself later acknowledge the trope and felt this was when the series was starting to run out of ideas.
