I have seen this a few times and still am amazed.  Try to do something like this at home and please make sure you are getting video taped so you can be in the next fail video I post.  Check out Anthony Pettis.  The guy does a running kick and jumps off the cage to get into the air.  I think the guy he was fighting was laughing when he saw him coming at him and then bam, he is down for the count.  How would you have tried to defend this?  TMTMTL@RollinSD.com
