Here's my funny gun manual story.
First auto, Beretta. I'm breaking it down, while a friend is reading the instructions to me out loud. (I'm paraphrasing the manual, so excuse inaccuracies)
Him: Now take the guide rod and spring out...
Me: Okay... *SPROING* as guide rod shoots across room, narrowly missing friend.
Him: JEEZ!! ...then it says: The spring is under tension, be cautious that the guide rod doesn't eject from the gun!
Hilarity ensued.
So I generally read any manual that comes with pretty much anything before I start using it. Most of the time.
