One word. Ash-2-Life. That bloody thing set me back for weeks. I nearly wen't crazy trying to find whata heck I was missing. I never bothered to investigate all the jars on the shelfs, since I thought their value was merely decorative (like the Cat Knuckles joke on MI1). Finally a friend of mine told me what I had to do, because he read the solution on a magazine. I still find this one of the most cheap frustrating puzzles ever present in an adventure game. MI2 is still my favourite in the series and one of my all-time favourite adventure games, but the Ash-2-Life thing still goes in my list for one of the worst puzzles I've ever encountered for it's lack of acessibility, being almost exclusively dependant random search.
Similarly to that one, was the laundry claim ticket on the back of Largo's room door. It also took me a while to find out that one, and it was almost by accident I found it. But despite being difficult to figure out aswell I found it to be a quite witty solution, so I actually consider it a good puzzle.
