Well, this topic has been dormant for at least a year. But since it was at the top of the page in it's forum anyway, I didn't see any harm in giving it a little bump.
After experiencing all of the Stooge shorts semi-back to back through the DVD sets, I have to say my least favorite is definately Bubble Trouble. I love the original version, All Gummed Up, but the new ending with the gorilla is just too painful to watch. And it just keeps going on and on. First time I saw it, I felt like crying.
Probably the worst non-remake short is Horsing Around. I have to say that I kind of thought it's prequel, Hoofs and Goofs, was a decent effort. This sequel, however, is laugh free. My least favorite non-remake Shemp short is probably Fiddlers Three, which wasn't all that entertaining.
I'm still trying to figure out what my least favorite Curly short is. I have a few ideas: Nutty but Nice, Beer Barrel Polecats, and Three Lone Wolves are probably my bottom three.
