Notice that the only really decent character is the bearded beatnik with the black girlfriend.
Seriously? He's pretty much mocked by everyone as the biggest hypocrite of them all. His pomposity on the bus full of black people, lecturing them about advertising and culture was unmissable.
Paul? Ugh! I hate Paul. He’s a pretentious loser. By 1967 he’ll have long hair, a handlebar mustache, and will call everybody “man”.
Roger is the most likable character on the show. Yes, he’s a total bastard, but at least he’s not pretending.
