I can always remember when we were younger all sat in the living room with my mates watching telly, when all of a sudden a great puff of smoke engulfed the living room. What on earth was that we all said Dad was rolling about laughing he couldn't speak when he eventually calmed down, he told us he had put talc in his undies and forgot then let one almighty rip which blew the talc straight out as you can imagine we have never forgot.
