Theres a couple round here (Bexhill on Sea is full of nutters!)
I remember this one old man who would always be talking to himself as he was walking but on this occasion he saw me park my car, open the door and put on my coat and all I hear is in an old git's from Harry Enfield type of voice was "oh, he's putting on his coat". He then starts to talk to me. He's ok really but rumous has it he pushed his mum down the stairs which killed her whilst laughing but got let off because of his mental condition
Just a rumour though.
