This sounds like the type of episode that could go either way - they could either do it very well or very badly. I'm cautiously optimistic, though. One thing we don't generally see from the SP boys, other then their continual poking fun at Cartman's weight, is issues of physical appearance, body image - it just doesn't generally go with the show's subject matter. So we'll probably have a chance to see a side of the boys that we (and perhaps they themselves) have never known before. For this episode, I can just picture some poor boy anxiously looking over his face in a mirror, wondering what's wrong....I can also easily see them trying to exact swift and terrible vengeance on the girls.
This episode may give us an opportunity to really see where the boys and girls stand in relationship to each other, and particularly, who may "like" whom. Has Stan truly gotten over Wendy by now? Does Bebe still carry a torch for Kyle and his "hot *ss"? Maybe we'll find out. Perhaps its partially because I'm a girl myself, but I'm quite curious to know that sort of stuff....
And I wonder what the list will say??? My hunch is that Stan will be deemed the best-looking of the quartet (or maybe they'll throw us a curve-ball and have it be Kenny, whose face no one ever sees). Cartman will of course be incensed at being ranked very low, quite possibly last, on the list. Kyle, I think, would be somewhere in the middle. Butters....it would be very funny if the girls actually thought he was cute, or if he was ranked higher than some of the other main characters. He'll almost certainly be ranked higher than Cartman, and I somehow don't think Cartman will take that very well.

For some reason, I think the girls will rate Token quite highly. (Hehe, Cartman won't like that either, if the black kid fares better than him. Oho, and won't he just love it if/when Kyle outranks him....

)
This episode, handled properly, has a lot of potential, I think.
