Monkey Island III: The Curse of Monkey Island - A lot of MI fans, myself included, have never considered this on par with the first two, but personally I still found it extremely enjoyable to play. I consider it The Return of the Jedi of the Monkey Islands.
Maybe it's the fact that this was my first Monkey Island game, but I still love this one. While the gameplay/puzzles weren't as good as the first two, I actually thought the humor was better. Then again, that might just be because of the fact that the spoken dialogue made it a lot snappier.
Also, speaking of those special editions, you can actually switch back and forth between the original version and the new one on the fly as you like. In fact, when the first one came out people were disappointed that you couldn't mix and match (i.e. play it with the old graphics but with voice-overs), so in MI2 they made it so you could do just that. I think it might be my favorite way to play.
