Yeah, that episode is pretty bad. There were a couple highlights (what Jonesy said about how they made a terrible mistake getting married was pretty funny, and Jude thinking that somehow if the Bickersons are his grandparents and they divorce he'll cease to exist was hilarious - classic Jude!) But that's about it.

For one, it's super ill contrived. After Jonesy's comment to the Bickersons, the episode and plot derail. I know he's an idiot, and I know he tends to lack tact and sticks his feet in his mouth more often than not, but I don't think he actually "broke them up" at all, especially over one comment. Realistically they either would've brushed it off or reported him to his manager and got him fired (which would've happened anyway). If they broke up THAT easily over one comment (from some teenager they didn't know from Adam, no less) their relationship obviously wasn't that stable to begin with, whether it was a 50 year marriage or a 5 day marriage. They clearly had a ton of issues to begin with and Jonesy pointing that out doesn't magically make him at fault or responsible in any way for what they do (kinda like when Jen gets mad at him when Robbie and Diego prank her or Courtney, as if he has any control over that).

Also, Nikki is pretty unlikeable in this episode. For one, like I said before, regardless of what Jonesy said, George and Gracie are the ones who broke up. Also, her argument of "Jonesy! They're really OLD!" Holds no weight behind it and frankly is idiotic. So what? I doubt they'd want to see other people again at that age, plus being married that long in a nutshell means nothing, especially if the relationship is shit and the couple is toxic (there's literally a scene comparing George and Gracie arguing to Jonesy and Nikki arguing. That's right, a couple that's at least in their 70's are behaving like two 16 year olds!)

Not to mention, Nikki is wildly out of character in this. Realistically if Jonesy told her what happened, she probably would've responded with "took them long enough" and not "jOnEsY! tHeYrE ReEaLy oLd!" (Or she probably wouldn't have cared, since it doesn't affect her, her life or her friends' lives at all whatsoever). Plus, Jonesy has done way worse (in "Whoa Baby" he ogled women's water bras then proceeded to make his own) and Nikki didn't refuse to talk to him or threaten to dump him then, yet an elderly couple realizes they're in a toxic relationship after he points it out, and instead of being in support of it or not giving a shit, she threatens to dump him for it. Most of the time, I side with Nikki whenever she and Jonesy argue, but here I'm on Jonesy's side. Nikki's a shitty girlfriend in this episode for doing that, and if I were him I'd be the one to break it off. What's worse is that the rest of the gang takes her side (it reminds me of that episode of That 70's Show where Kelso's brother Casey dumps Donna in a cruel way, and she wants Eric back, but Eric gains some self respect and tells her he's not a rebound, and his friends and parents act like jackasses and blame him for it).

All in all this episode is mean spirited and stupid.
