The loser provides full broadcast-quality play-by-play commentary of mundane activities, the office microwave line, a grocery checkout, geese in a park, for a day of clips. Color commentary partner optional. 'He's going with the 2% milk, a bold choice given the matchup' is the energy required.
Budget note: this one costs nothing but dignity, which makes it a strong pick for leagues that would rather spend the pot on the champion than on the loser's downfall.
