A lot of humor today is simply “Republicans are stupid” and “White people are stupid”. You don’t need a build up or a punchline. People are aware of what they are supposed to laugh at, and they comply.
I had to transcribe a “comedy” routine not too long ago. It was a gal in a night club in Denver. There was a good-sized crowd. On the video, she was showing - for example - trappers skinning fur animals while she was telling “jokes.” One of the jokes involved her - not making this up - putting a hot dog in her v4gina, then taking it out a couple of minutes later and eating it.
The laughter from the crowd - again, it was a decent-sized crowd - was spotty and not very enthusiastic. Like someone was holding a gun to their heads.
