Character mistake: The undercover cop who first mistook Chrissy for a hooker, first admits he was wrong about the way he judged her. Then upon finding out that Jack lived with her and Janet, he came on to her instantly thinking she's "easy" once again. However, the cop was already informed by Mr. Roper that Jack was gay at this point, so the fact that a "gay" man living with women should not have changed the cop's mind of how to view Chrissy the way he did.
Will the Real Jack Tripper . . . - S2-E21
Character mistake: When the angry father comes to the door at the end of the episode looking for Jack, Mr. Roper opens the door and after the father asks "Jack Tripper?", Mr. Roper responds "Yes" and then gets chased around by the father assuming Roper is Jack. Why would Roper respond "Yes" anyway? He's not Jack and would never say he was - just scripted as a way to get chased around but in a real situation, he would have no reason to answer that way.
Character mistake: When Jack is tending bar, the one woman states margaritas don't include tequila, when it's the primary liquor.
Suggested correction: This is from s02e10, "Stanley Casanova." However, she doesn't say margarita, she says daiquiri, which is what Jack made with tequila. Daiquiris don't contain tequila but typically rum.
