I can understand someone not "getting", or even "getting but not liking" Brother Theodore's act, and sadly, television talk shows were not really the form in which he shined. His one-man shows, several of which were recorded, show someone who knows what he is doing, and it's basically sort of a horror/humor act, but he really was not one to do discourse with other performers in an informal, ad-lib sort of session.
Here is a better example of what Brother Theodore did:

And come to think of it, he may have been more personally well thought of by more folk than Jerry Lewis was.
