Dead Pool and Death Pool

The character of Deadpool Marvel Comics and movie fame takes his name from the term dead pool, originally death pool — originally a sum of money put aside for the family of someone who died in a high-risk race such as car racing, then later became a betting pool predicting when certain people would die. The term also denoted a payout to the family of those in high-risk occupations like police officers. The expression was further popularized by the Clint Eastwood film The Dead Pool starring Liam Neeson. This is part of a complete episode.
