There are many, many characters in The Simpsons. They're all great, and they're all funny—but that doesn't mean that they're all upstanding citizens of Springfield. Some of them are nice, and a bunch of them aren't so nice. After all, a community worth watching for 36 seasons is going to have its fair share of characters whose self-interest drives them more than anything else. Even members of the Simpson household can be pretty selfish, usually Bart (Nancy Cartwright) and Homer (Dan Castellaneta). These two can be among the most selfish characters in the series, even, but it very much depends on the episode. Sometimes they can be very selfless, and sometimes it's a mixture of both.
