In the 90s, there were serial daters with their own shows. Cheers had Sam, Friends had Joey, Frasier and Seinfeld had their title characters... it was a thing. It brought fresh faces to the sitcoms for a stretch of episodes, and then they were replaced with new ones. Hot in Cleveland has had that, too, but it's getting extreme as well as boring. Revolving boyfriends, extended family members, coworkers, and even neighbors have been appearing on this comedy, and as soon as a viewer might start laughing at someone, they're out the door. As soon as one of the four ladies might start growing because of someone they're frequently with, that process gets shut down. There's something to be said for sticking with the initial premise of a show, but there's also meat behind the idea that change is good.
J.J. wants Victoria to meet his grown children, Jessica, James, and Lisa. Victoria tries her best, but manages to upset each, and then when she reminds J.J. too much of his ex-wife, they decide to take some time apart. [well, that was a quick relationship! It was kinda destined to fail from the start, though.]
Also, Joy and Elka both fail an oral exam, but decide to listen to Frankie and suggestively blackmail the teacher into passing them. It works.
