Corrected entry: To avoid conversing with Cindy about Cindy's alleged pregnancy, Janet picks up an ashtray off the table and claims it's filthy and runs with it into the kitchen. None of the roommates were known to have smoked and no ashtray was seen (in the apartment) in any other episode. What was the point of an ashtray all of a sudden?
Corrected entry: Jack tells Mr. Roper (while at the Regal Beagle) that the women in the Beagle are "fantastic." Roper gives Jack a strange look (about his acting straight instead of gay, which he always thought Jack was). Jack then corrects his sentence (using gay personality and gestures). Roper is no longer the landlord of Jack's building so Jack didn't need to correct himself in front of him or care if Roper still thought he was gay.
