I just moved to the Bay Area and watched the new South Park which picks on that city. I almost died laughing. Matt & Trey got the city perfect, full of smug, self-righteous adults who enjoy sniffing their own farts, and their kids who take lots of drugs.
While hybrid automobiles emit much less smog, the problem is that the people who drive them emit lots of smug. San Francisco already had the highest levels of smug in the country, but when the people of South Park begin driving hybrids, their smug is so great that after combining with George Clooney's smug it threatens the whole planet.
And it's true that everywhere you go someone offers you acid. That's what I love about the city, I never want for bud and hallucinogens. Absolute paradise. We're so much more progressive than y'all...
