Stacked it on Saturday night in my lounge whilst gibberingly drunk. I was carrying a bottle of sloe gin (I made sloe gin, not sure if I've mentioned it...) covering two white walls and a cream carpet. Due to incredible levels of speed and elbow grease, neither of which were mine, it's nearly all gone. Maybe not the worst stain then but I'm not retyping this.

Your worst stain?

(semen!!!!!)
