When I was a kid, I remember watching some detective show on TV where the murderer had "dunnit" by electrifying the metal handrail of the "dunnee's" shower, so that when he or she (can't remember which, but it's bound to be one of them) next took a shower, he or she would touch the rail with lovely wet hands and be killed.
Shortly after I had seen this masterpiece of televisual art, we had a shower installed – with (of course) a metal handrail.
I was convinced that the handrail would be electrified because I'd seen one just like it kill someone on the telly (I didn't realise then that someone else had rigged it up and, in fact, the whole whodunnit part is a sort of ex post facto rationalisation of my adult mind, based on a very dim memory).
I even convinced my little sister not to touch the handrail as well, so we spent our formative years balancing precariously on one foot whenever we needed to wash the other because it wasn't safe to touch the rail.
Never underestimate the power of TV on young, impressionable minds (and old ones, come to that).
Has anyone out there had a similar "'cos it was on the telly" experience?
