Aaron tells Mike about 'White Collar MMA'. Fights for people with minimal experience to raise money for charity.

At Aaron's first MMA class, he is picked out by Scott to try some ground escapes. He performs the first two quite easily and Scott learns he is a Karate student and challenges him to one more technique. Scott almost has it and begins a speech about MMA's superiority, but no sooner has he started, Aaron escapes the hold and gets Scott in an arm-bar. Forced to tap, Scott challenges Aaron to take him down and submit him with a different technique, without hitting him. Aaron manages to do so and Scott locks his arms up and punches him in the face unless he taps... then he ignores the tap and keeps punching until Aaron is out.

After Aaron fights to a draw in his match, Mike and Scott fight. With Mike still suffering from a back injury, Scott is able to take full advantage. But in the final round, he taunts Mike and it does is remind Mike of something he recently taught. Mike snaps into action and uses an application from Bassai Dai to throw Scott through the air, mount him, and trap his arms in an arm-bar. Feeling Scott tap, Mike hides his hands under his own armpit, then punches him in the face as he did to Aaron previously. Scott's arm breaks and the ref steps in to finish it.
