Thats actually really funny!!!
One time over the summer I was hanging out with my neighbors while they were skating and one skated over his finger and it was bleeding so he let it bleed into a cup of water and then set it in the grass. I went home to get a CD and when I came back my other neighbor started skating really fast towards me and I didn't want him to hit me so I moved into the grass and tripped over the cup of blood and I had blood ALL OVER my legs!!!!

It was gross
