There used to be a chap in Nottingham in the seventies who dressed in full English civil war regalia - I forget which side if I ever knew - including Friday and Saturday night round the pubs.
One evening on the bus home the local lads went too far with the piss taking and he shot one! The pistol was loaded with powder not lead but he ended up in court and the comedian got powder burns.
I also recall at least one air whistle player. My favourite was a well-dressed city type who caught the bus on Southampton Row, London, similar period and read a comic with matching facial expressions, shouts and cheers to the adventures in the Beano, living out every jape and pratfall.

The world is too small for such people. Since back into the community initiatives I notice no let up in the nutter supply. Given reality, can you blame them?
