Chessboxing???

I saw a flyer for chessboxing in Berlin next weekend. I may go check it out. I'm not sure yet. It seems very interesting and unusual at the same time. Have YOU participated in/watched/heard of this hybrid sport?  What do you think? Was it fun?  Would YOU attempt to play???

I can't imagine trying to make logical and legal moves after doing a few uppercuts.  Seems very intense.

If I go, I'll post some fotos and whatnot.  Just thought I'd share my random thought of the moment.
