Speaking of manhole covers, when I moved to Canada there was no internet. So I couldn't easily look stuff up. Stuff like manhole covers.
Me and a friend were playing Police Quest 2 and we couldn't figure out what the hell a "manhole cover" is.. The game wanted us to investigate one. Well.. We know what a man is, we know what a hole is, and we know what a cover is. I won't even say what we thought it might have been.. Men only have so many holes in their bodies after all..
Let's just say we were pretty upset at the English language after we figured this one out..
