You talk about Joe Grizzly, and that's definitely a standout part. I can't really think of many parts in any of the other movies that really made Myers looks like the engine of destruction he's supposed to be, but that part where he repeatedly slams a very large man into a bathroom stall until the stall wall actually crumples is pretty brutal. Also gotta shout out to the crushing-the-stripper's-face-against-a-wall scene from II.
