I have seen all but 3 episodes of season 6 and I can safely say that I enjoyed all of them, other than this episode. I don't know what this episode was supposed to parody, or even if it did parody anything, but it wasn't funny. Stan, Kyle, Cartman, and Butters go on a ski trip and meet this dick who targets Stan for no reason and is dating somebody who he thinks is Stan's ex-girlfriend, even though he never met her. He challenges Stan to a ski race, and beats him. And there's this community center that's about to be taken down, so Stan rematches the guy, wins, saves the center, get's his not girlfriend back, yada yada. The point is why? What was the episodes point? I never smiled when I watched this episode. It seems like it's just a bunch of older people focusing on Stan because he exists. The whole main plot is just one joke. Stan and some of his friends lampshading that he doesn't know these people, and it got boring fast.
The sub-plot is also lame, but not nearly as bad. There's these two insurance guys for time share who repeatedly get the parents into meeting into buying a condo. They try to leave reoeatedly, but always fail. And then when they call the police, it turns out they're working for time share also, and threaten Randy and the other parents with guns. Next scene they appear in, they're perfectly fine. They bought the condo out of force, but my problem with the sub-plot is that it feels rushed all together, and the only real comedic aspect is the parents getting annoyed. Also, what is up with one of the community center people and her mutant breasts? What's that supposed to mean?
My recommendation, don't watch this episode. See the other episodes of season 6. They were hilarious. This was not. It's probably funnier if you know what they're supposed to be parodying, and maybe if I saw the thing they parodied I would like this episode, but since I didn't, nor did they even bother to add jokes outside of it, it feels more like a bunch of idiots focusing on Stan for no reason. This is an episode that's about as lame to me as the season 1 and 2 episodes. Rushed, unfunny, and overall, boring. 2.5/10
Note: I probably didn't explain the plot enough, but I don't know how to put it in any other word, and with the word limit on tv tropes, I'm pretty limited.
