Other mistake: In the Regal Beagle, Jack addresses Marsha as Ms. White although later in the episode her last name is revealed to be Whitewood. In addition, how could Jack have known her last name anyway? Marsha only said her first name in front of Furley and the trio early in the episode and presumably she hasn't talked to the trio since she left with Furley out the door.
Suggested correction: In addition to the other correction (occurring 00:07:25), this correction addresses the second part of the mistake, as to how Jack knew Marsha's last name. Earlier, when Larry tells the trio that Furley was fine with him being late with the rent, Janet states, "He's been wining and dining her for 3 days" (at 00:06:15). So at any time during those 3 days (offscreen), Furley told the kids about his dream girl, which would have included her last name.
Suggested correction: No Jack does say, "Hello Ms. Whitewood!" While they are shaking hands. Time stamp in the episode when this occurs is at 7:25.
Other mistake: After Jack leaves The Apartment with Mr Angelino, Janet and Terri are sitting on the couch trying to figure out a way to get money for Jack. When Janet gets up you can see the bathroom door start to open behind her but there is no one else in The Apartment to open it.
Grandma Jack - S8-E7
Other mistake: Larry entered Jack as "Grandma Tripper" to win the contest since the contest was only open to women. However, since Larry admits he didn't know there would be a bake-off and thought a winning check would just be mailed, then there's no reason to of entered Jack as "Grandma." He easily could have just entered Janet or Terri using Jack's recipe.

Other mistake: John is wearing a dental retainer during the closeups of Jack talking on the couch with Chrissy.
