SOMI: The whole thing was uniformly good. I don't thing any moments especially stand out, oh wait destroying your ship was funny and it was interesting playing through again to find that the game pans out slightly differently if you don't.
MI2:LR: Again the whole thing was truly immense, for some reason I find the Guybrush sinking to the bottom of the ocean funny, not sure why but I do. Also "Arrghh we don't need no stinkin' mouthwash".
COMI: I didn't enjoy this game much, the whole thing seemed a bit lame and forced and I didn't particularly like the cartoon style. I still thought it was okay mind, just not as great as the others. Nothing stands out.
EFMI: "You've befouled my platypus". A classic line. As was "its a brass monkey (audience) Brass Monkey Monkey.
