So, did you ever hear the one about Veronica Mars and Chlamydia? It goes like this. There was this girl named Veronica Mars. She went to the doctor. The doctor said she had Chlamydia.

OK, so maybe that wasn't funny, but it's true. Veronica's doctor told her about the diagnosis, and being told you have an STD is bad enough, but for Veronica, who hasn't really had any sort of love life besides the kind you find in the top drawer, it's has to be even worse. If you get an STD when you're sexually active, at least you can say that you had some fun getting in trouble. Unfortunately, since the symptoms may not show up for months, if at all, Veronica has no clue how she might have contracted the disease, especially since she said she and Duncan always used protection. Besides, Duncan wouldn't cheat on her, would he?

As Veronica said, the saying goes "When life gives you lemons, make lemonade", but she can't figure out anything to make if life gives you Chlamydia. But as bad as Veronica's problems may be, Mac is the one living the nightmare. She is stuck going to the prom with Butters. Being the principal's son is difficult enough when you are cool, but when your biggest claim to fame is a radio show of declining quality, life can be hell. Is one cell phone interceptor worth all of that trouble? The prom is one thing, but dinner on a replica pirate ship? That is a whole different ballgame.

Is there any hope for Mac? Well, aside from suggesting Medieval Times instead of a pirate ship, there isn't much she can do to get out of this. Luckily her classmates have decided to help her out, although in an indirect way. There were so many alcohol violations during the senior class trip to Magic Mountain that they administration has decided to cancel the prom.
