Evil Roy Slade

I saw this movie late at night on television while visiting a friend in Los Angeles in the mid 1970's. My friend was actually rolling around on the floor because he was laughing so hard. Although I haven't seen it since, I still remember it as the funniest movie I have ever seen. Maybe it was partly because it was late at night, but we were both sober. I think it was much funnier than Blazing Saddles and much less offensive. After thirty years, some of the scenes are still clear in my mind, such as Slade taking off all his weapons or persuading his horse to make the jump over a wide ditch. It's almost like an American Western version of a Marx Brothers movie. I don't remember anything dirty in it, so even young children would enjoy watching it. I'd really like to see it again myself.
