yea man i agree with ahmonrah and baby j. you should be above the fact that you just wanna flex on him. do it legally. i've done martial arts for about 10 years, and its at the point where you don't really ever wanna fight.

besides if you beat his ass, you're still out 600 dollars, and still out of a job, and car. bruises and broken bones heal. in the end he'd still have your 600 dollars.

do it the right way.
