Chess Boxing

I am not a big fan of boxing game. So not a fan of Rocky series movies. In fact i don't like to watch games (except for gymnastics, swimming etc in olympics). Even in my undergrad days when most of the students will be in hostel common room watching cricket, i will be sitting lazily in my room reading some novel.
So in the last issue of Time when i saw an article on Chess Boxing, i was amazed. This was the first time i heard/ read about such a game. In this game oponents will first throw boxing punches at each other for 4-5 minutes and then will immediately start playing chess game. Winner is decided by knockout, checkmate and by refree. This is really interesting. And there are tournaments organized for this game.
This prompts me to think, can i mix some other games and start a new game. What about mixing swimming with tic tac toe. First swim one lap and then draw a circle. :-)
