It's two bounty hunters, Spike Spiegel and Jet Black, who live on a ship named Bebop. Over the course of the series their "team" expands to five members including a dog named Ein, an odd computer prodigy child named Edward, and a bounty hunter/gambler named Faye (who happens to be my favorite female anime character EVER). The series as a whole follows each character's own separate storylines, as well as a bunch of strange side plots. A lot of really cerebral material as well as just plain goofy humor. Overall, I'd place it as my second favorite anime series. I bought the box set in December, and it's worth every penny.
