>I'm specifically thinking of the "Monkey wrench" puzzle from Monkey Island 2. Let's just say that as a kid, playing the French version of the game, getting past that part of the game was quite frustrating.

Touchè for the german one. Years later I finally understood the joke behind the puzzle after finding out the english/americans call that specific tool a monkey wrench. In germany we call it "engländer" (->english man) but it seems that sometimes or in someparts of germany they call it "franzose" (-> french man)...
