True story time.
Back in college my roomate and I got into a argument over some baseball trivia. I got out my (hardback) edition of the Guinness Book of World Records to prove my point (I don't remember what the question was). Anyway, he got ticked off about being proven wrong, so he took the (hardback) edition of the Guinness Book of World Records and smashed me in the face with it, shattering my nose.
Now to the funny part.
After the cops had left, I was still bleeding like a stuck pig, so I was walking the two blocks to the campus medical center was located when a car pulled next to me. The fellow behind the wheel put his window down, looked at me (including all the blood on my white shirt) paused, then asked me where the performing arts center was on campus. While holding my nose shut I, being the nut that I am, went on to tell him exactly how to get where he wanted to go.
He never even asked if I was ok.
