Making a bathroom or preferably the entire structure as warm as possible after a dry-dock deluxe so as to promote the most un-godly smell possible. Close all windows on the hottest summer day and turn the AC off and the furnace on full blast. This works especially well on mobile homes and travel trailers. The longer it bakes the more permanent the stench. If done properly it can result in the structure being torn down.
I totally made this jagoff's camper a Hot Tank while he was out fishing. Man that had to be bad when he got back, it was like 95 degrees and there was no shade!
