I remember when I broke my hand. I couldn't play for almost 3 weeks, and it hurt a bit after that. It sucked big time, though I actually stopped being such a monkey's hind end because of it.
Here's how it happened:
I was in Indio, CA for the first Cochella festival. My soon-to-be girlfriend and I had flown down there but I'd left my wallet at my ex's place (passport ftw). She was a broke arsed 'ho, so we ended up camping and not eating a lot (which is fine, I'm not snobby). After the festival, we missed the bus we needed to get to the airport because it was some holiday and the posted schedule wasn't correct. The airline wanted to charge us 50 bucks a ticket to switch flights. Well, I called my ex and asked her for my cc # (it was a new one and I didn't know it) and she raged on me and refused to help because she was jealous. Long story short, the airline lady felt sorry for us and switched our flight for free.
This would be all fine and good except there was construction on the bus route, and we missed the second flight by 15 minutes. The phone gal laughed and switched our flight again. We camped out at the airport and then decided we needed some food. We scraped together our money and went to a taco truck. I kid you not, someone stole my female companion's bag (with her ID). Now, one of the guys who worked at the taco truck was smoking and saw it, so he chased the guy down and got it back... like 15 blocks. The cops stopped them and we all had to give reports. By the time it was all over and we were walking back, we'd missed the flight... AGAIN.
THIS IS WHERE I BECOME MORON-MAN, DESTROYER OF GUITAR PLAYING: I was really, really cheesed off. Walking down the sidewalk, I saw this unassuming cheap aluminum ashtray mounted crooked on the side of the building. Surely it was no match for my fury. I punched it as hard as I could; intent on doing major damage. Ok, so, as I'm sure you've guessed, I did major damage. No, not to the ashtray, which was in fact brushed steel (and mounted more securely than any man would be to Marisa Tomei's backside) and not aluminum. I broke 3 bones in my hand, and I actually heard them break. My future girlfriend just looked at me and said, "that looks like it hurt." And I just said "I don't want to talk about it... that was really dumb of me."
So, I ended up calling my brother who wired me money, went to my ex's to get my wallet, and laughed at me. I spent ~3 weeks in a cast, and strangely enough, I think my playing improved because I couldn't play... I had to listen and imagine.
Anyway, enough blathering.
