Ricks' note about the pointed humor of Benny and Marx is right on. I, for one, adore Groucho and the Bros.---but in a few of their films the steriotypes and racism is obvious. But, everything, I suppose, has to be put into the context of its time.
Now to Rick's earlier comment---Brother Theodore. Just Theodore before the monicker stuck because of the Merv Griffin show. An amazing performance artist and a great teller of tales.
Check out his website---it will amaze.
And, in the words of Theodore----intelligence in my audience is as rare as rocking horse manure.
