I'm a big Marx Brothers fan too. I've never read Harpo Speaks but, like Auntie Christina, will pick it up if I ever see it used.
I guess I'm in the minority, but I like Laurel & Hardy too. I mainly like the shorts, but I like The Music Box too. I can see why people don't like their stuff, and I do often find Stan Laurel too broad. I think Oliver Hardy is a really terrific comedian, though. He's the reason I watch.
