I work in the factory of a midsized candle manufacturer, and one day we got a call from a very nice man who said that one of our container candles had shattered while being burnt. The guy that handles such things was asking him a couple questions over the phone and when he asked if they'd been trimming the wick regularly while burning there was sort of an embarassed silence... the man told our guy that um... well... just perhaps the wick had gotten too long because they were in bed at the time and some of the wax had been poured out of the container and this wasn't the first time it had happened to them, and no not just with our candles. Our guy told me this (and yes, he's rather naive) and I burst out laughing. I ended up having to explain that there are people in the world that enjoy dripping wax onto each other's bodies as a turn on. Boy was his face red, and I think mine must've been also just from realizing how much I had shocked the poor guy. We did send the nice man a free candle, and our guy gave him a nice lecture about how maybe they should consider keeping something to trim down the wick by the bed.
