Bebop is awesome. Mind you, each episode is more of a loose adventure, there is no overarching plotline
If you're more into fantasy-massive plot kinda stuff, Full Metal Alchemist: Brotherhood is the thing to go for. The dubbed version is actually pretty decent. It's on Netflix, too.
Black Lagoon, if you want a more hardcore, gritty series. Very bloody, very explicit, very dark. Also extremely good. My personal favorite.
If you want some random shit, try looking for the Ghost Stories dub. When dubbing, the script was completely tossed out, and replaced with random shit. It's really just an official Abridged series. These
