Poignant BFS Story
One of my favorite things to do is to go out in a stiff breeze aboard someone else's boat, preferably with more than just me and the skipper aboard. When the skipper goes down below to use the head, I wait a few seconds for things to start flowing, then I sheet in REAL tight and come up to a beat to get the boat as far over on its ear as possible. This, of course, takes the skipper by surprise and causes him to have to pee uphill, sometimes drastically so. Sometimes a tack is required to accomplish this.
When the cursing from down below stops, I hand the tiller over to some unwitting dupe, take a position on the rail far from the means of steering, and affect an air of supreme innocence. Sometimes a dose of pensive horizon-gazing is required to complete the illusion.
This doesn't work so well on your own boat for obvious reasons (relating to having to clean up).
