Oh jeez. That set was pretty tame relative to the club comedy scene in big cities. Shock is a pretty common component and a goal for some comics. For this guy, it’s practically his whole brand. Not everybody is Nate Bargatze.1. I've never seen a comedian do that. Maybe it is something that asshole comedians whose audiences are assholes does, but even there I'm doubtful.
But if you’re not in the comedy clubs or plugged into the stand-ups podcast world then I guess I can understand it being surprising.
