Knock out ginger in Knowle definitely - one poor bloke in our road (we lived in a cul-de-sac), was relentlessly the victim of this back in the 80's (due to him living by a lane that led out of the road, and putting butter on the rails that prevented bikes racing down to stop us sitting on them, after that he was fair game he had the lot, sellotape, blu-tack, superglue no substance was out of the question for his doorbell after that)
