I also watched this episode and was amazed at how Jerry Lewis wasn't able to say a word. When they went to commercial break you could see how upset Lewis was. It was a very strange situation. It appeared that Cosby was purposely trying to hurt Lewis. Every time Lewis tried to say something Cosby would cut him off. I always remembered this show and looked for it recently to see if my memory was accurate. The fact that someone else had the same reaction makes me sure that my original impression was correct. Cosby was a guest host and you wouldn't think that something like this would happen especially with a big star like Jerry Lewis.
