This is a bit awkward and weird, but I do have a picture to finish off the story.
Every year in our town, we have a semi-large festival called "The Steel Bridge Fest"... It's pretty much a bunch of different music for three days to raise money to preserve a bridge. Our band, Phenomenecronomicon, got our start there. It was the second year and we were invited to play again, so we accepted. We got on a crappy stage in some semi-abandoned building... Our set went pretty bad, and I pretty much stripped down to booty-shorts and was hitting my drums as hard as I could, and punching my cymbals. Afterwards, my lady-friend and I went to the band van, and we just talked for a little while. She stepped out and I had to pee, badly. I didn't want to go outside and run the risk of getting a ticket, so I found a bottle. Well, the opening of the bottle is a tad bit small, and it was dark. I start relieving myself, and I start to hear a whistle. All the sudden, pee goes everywhere. EXCEPT for on the van, just all over my clothes. I called my girlfriend over, as I just had an accident, and she thought taking a picture was a better idea.
And yeah, that's pee in the bottle. I dunno why it looks like blood, though...
Oh, and our guitarist wasn't the happiest when he heard about what happened, but I was able to prove not a drop ended up in the van.
