The page title shows up in the search as "buy propecia price - NMSU Library". My guess would be some sort of old HTML injection attack that's been cleaned out, but which hasn't fully flushed out of the index.
What's really odd is the two college sites below that, which don't have anything obvious about Propecia on them...
Probably had their CMS hacked or something. That sort of thing happens to a lot of sites, sadly. Google for "comment3" (make sure there's no space in there) and look through a couple pages of results and you'll find a lot of spam-filled sites. And that's after Google cleaned up a lot of it.
