Interesting in other social ways as well — Groucho was allowed to (literally) "cat-call" the attractive female guests on his show.

I suppose there was a sieve that their guests went through but it is still fascinating to see the parade of suburban Los-angelites: housewives, people with strong ethnic ties to the "old country" that had yet to be melted into the pot that was 1950's America. Who knew door to door salesman really was a typical working class occupation?

Oh yeah, all kinds of baggage attached to the last bits of the vaudeville Borscht Belt. That's also something that makes the transition from Allan Sherman to Weird Al Yankovic so jarring; they did the same act, but even aside from production values, Weird Al didn't bother dragging a previous audience along, and was willing to go anywhere.
