Truly a unique theme to you? Most everyone I know ( at some point during their foolish youth ) has played the hypothetical game of "What Would It Take For You To..."
ie. Cut off your 5th finger? $500k? $750k? Or shave your head for a year?
Of course, the men would ultimately get more graphic and violent than the women, but it certainly invoked an interesting thought process over the years.
Different, yet somewhat similar.
