Apparently, it's supposed to be lucky, although as ocean_song says generally by the person that did NOT get shat on. Sitting outside the pub tonight with a lovely glass of beer, I heard two wet sloppy sounds in succession. The first was the pigeon in the tree above crapping on my head; the second was it bouncing off my head into my beer! Distressed as I was by the experience - and by the waste of beer! - I am also very impressed by the pigeon's aim! Does this pigeon practise? How often does it score a double? Does it add up the points?
