The thing that makes me the maddest is the fact that Curly-Joe actually admitted he didn't think the Stooges were funny. It's in the Three Stooges Scrapbook. I think that may be why he was the least funny of the Stooges. He just didn't get it and he made no attempt to.
I just watched Triple Crossed last week and as a good example of overly-used stock footage, Moe has no new scenes until 13 minutes in! But another problem that I see with the Joe shorts is that they are no longer complete morons. When one of them says a joke, they realize its a joke. When Joe uses the "Fine For Hunting" jokes in Guns-A-Poppin', Larry scoffs afterward, instead of agreeing with him like he did with Curly. Also in that same short, Joe says Moe is nuts for eating his eggs sunny-side down, and for eating spaghetti for breakfast. In the earlier years, thise were just Stooge-isms. In these shorts, they seem more like eccentric old men rather than stooges.
