I read that! I found it highly amusing, but not as good (or bad?) as the Sue Ellen x Fern as teenagers slashfic I found - that was pure gold, intentional or not.
THAT'S IT!!! That was the fic! Yeah, I remember now the main plot had to do with Sue Ellen and Fern basically trying not to get caught while trying to almost get caught at the same time, but still, Buster and the drugs, and those secondary colors were hilarious... and when he jumped off the balcony of his apartment trying to fly or something. XD
I don't usually read slash fics, but I've often thought that Fern and Sue Ellen would make an interesting slash couple, I kind of wish there were more fics about that.
As for couples, who do you guys think should be with who? The only thing I can think of is Binky and Sue Ellen seem to have some hidden irresistables for each other, especially since Binky wonders if she's written lovey-dovey stuff about him in her lost diary... but in that same episode, Sue Ellen gives Arthur a not-so-subtle hint that she's written nice things about him. But also, they often seem paired together in stories, like when Binky went obsessive compulsive over that butterfly. And so many people like to think Arthur and Francine should end up together, I think at one point, someone edited Wikipedia to say that Francine openly had a crsh on Arthur, but that of course hasn't happened, they may haven taken the square dance episode out of context (where both Arthur and Francine are lead to believe the other is in love with them).
