There was a thread a couple of years ago that got so contentious the entire thread was pulled, which almost never happens. The entire story never came out, but here is the gist of what did come out. Two guys were fishing all day, accompanied by a number of beers--the exact number unknown. As dusk approached, they decided to grab a scuba tank, a spear, etc. and drop down to about 200 feet where the big fish are. They separated, as is common when spear fishing, so the one who made it back had no way of knowing what happened to the one who didn't.
