I'm sure I watched some of this when I was quite young, but I'm afraid I really don't remember it well enough to comment on. You should know the basic concept though. There was this scientist named Dr. David Bruce Banner (played by Bill Bixby), who got irradiated with like gamma rays or whatever, and then whenever he'd get mad he'd turn into this big green monster guy called the Hulk (played by Lou Ferrigno). I haven't really read much about the Hulk in the comix, either, so I dunno how close or different the show is from the comix. I would guess fairly different. Anyway, Dr. Banner was like always on the run or something. Helping people out, trying not to get mad, and stuff. I dunno.
There's also a movie called The Incredible Hulk, which is not directly related to this show, though of course it's about the same character. And there was at least one point in the movie where a bit of this show's iconic music can be heard. And Lou Ferrigno had a cameo in the movie, as a security guard.
