I'm not GP, but I've played a few adventure games and was very excited to try Monkey Island because of its sense of humor and style. But it felt basically unplayable to me (basically it felt like the only strategy was brute force), here's the puzzle that made me give up:
Give the jawbreaker to Blondebeard to loosen his gold tooth, then give him
the pack of gum. When he blows the bubble with the tooth in it, pop it with
the pin and the tooth will drop out. Get the gold tooth, then exit the shop.
(To get the gold tooth on Mega-monkey, chew the pack of gum to get the chewed
gum. Inhale from the helium balloon, use the gold tooth in the chewed gum and
then chew the tooth in gum. It will float out the window of the shop and land
in the mudpuddle outside. Use the pie pan in the mudpuddle to get the tooth).
