Weird early 1960s man on the street interviews in San Francisco?

I remember hearing this weird radio show thing where this guy would pretend to be a reporter and then ask people on the street bizarre questions. I think it was in the 1960s.

One thing I remember, I think they were asking this black guy (?) something insane about a group of "maniacs" in some really bizarre scenario (like the maniacs were in some Bruegel-esque hellsscape.

Ring any bells? It sort of had proto Joe Frank vibes.
