Look at him in the first 3 seasons (the only ones I consider canon):
He asks for a job, has a salary, goes to the supermarket by himself, lives alone, hangs out exclusively with people who also live alone, cleans his own lawn, could afford a car, does racy offensive stand-up comedy (every kid's favorite!), pays for cable TV porn, owns a big library, goes on strike, tries to get into a bar, lived in the wilderness, drinks coffee alone in diners, got arrested multiple times, and his favorite nostalgic childhood TV show is so old that its stars are in a nursing home!
