Absolutely right about Harpo ~ I couldn't have phrased it any better myself. (I know, because I tried!)

I saw "Night at the Opera" recently, too. We were probably watching TCM at the same time. I believe they showed it that night because the interview aired earlier that same evening featured Bill Murray talking about, among other things, his favorite moments in movie comedy ~ including that film's famous stateroom scene (where so many people are jammed into a tiny space).
