Best I've seen was on a Midland Mainline service to Sheffield that got held outside of Kettering due to a trespasser on the line (he actually walked right down the side of the train with BTP following at a distance). Anyway, there had been two announcements by the train manager explaining why the train had stopped and apologising for the delay when someone comes belting down the train screaming "let me off, let me off, its a short platform!" obviously thinking that were were in Kettering station (I've no idea if Kettering has short platforms or not). Brought a smile to my face as looking out of the window either side all I could see were fields and we were obviously still dome distance away from Kettering station.
