We bought a Monkey Farts Candle and snuck it into the house of a family member hosting a Christmas party. While everyone was being social I excused myself to the bathroom where I left the candle in an inconspicuous location on the sink vanity. We said nothing. A week or so later a group text went out to the family asking who left the candle. We still said nothing and unless they read this review they may never know. :)
