Yeah, that bus is a rolling circus. check out one of the wilder scenes:
Best Bus Line San Francisco 2000 - 22 Fillmore
San Francisco's eclectic nature is showcased on a ride up, down, and over a wide array of city terrain. The route starts at the Marina Green's bay shore, proceeds across tony Cow Hollow, and staggers uphill into the even tonier splendor of Pacific Heights, where the vistas out the bus window are staggering. Coasting downhill you pass Japantown, the Western Addition, and ever-groovy Hayes Valley before crossing Market into the even-groovier confines of the Mission. Then, making your meandering way eastward you find ourselves on the fringes of Potrero Hill, south not only of Market but of China Basin (how hip is that!), until the party's over at Third and 20th streets, leaving you once again on the shores of the bay. Your fellow passengers may appear alarming now and again, but remember: So do you.
