First off SAILOR MOUTH is an amazing episode, but I don't think a child would really understand why it is so funny. Then there are some other really good ones. Like the one where patrick and spongebob raise a clam. Then there's the classic episode Nasty Patty. Then Just One Bite, Fun, Dying For Pie, Help Wanted, The texas one where sandy wants to move back too texas, and a ton more. I actually like some of the newer stuff too, though. Like the one where squidwards trying too win house of the year or something, and the one where spongebob shares a locker with squidward, then the one where spongebob and patrick shave off the flying dutchmans beard, Then the one where plankton dresses up like an old person to try and steal the recipe, and a ton more.
The movie wasn't that good though, too be honest, and those 3 or 4 years of post spongebob movies were not very good, but it did start too pick up a little more recently. I mainly watch it, because it's something I enjoyed a lot as a kid, and even now I can enjoy it, aswell as understanding how adult this show really gets at times.
