Laura Bow II! I used to replay that one just for the music (I'd even bounce around my apartment to it.. hehe.. that was back in my college days when I used to multi-task between adventure games, IRC chatting, and schoolwork into the wee hours of the morning *sigh*). The crazy dialogue didn't diminish in appeal with repeated reads/listens, either! (I found a few easter eggs along the way, too, which made it all the more fun.
)
Also KQ 2-6, mostly five and six.
