Few people have made a deeper impact on the sport of mixed martial arts over a longer period of time than Dan Caldwell, Tim Katz, and the late Charles Lewis.
Better known, respectively, as "Punkass," "Skyscrape," and "Mask," three friends from Orange County started a business selling t-shirts out of the back of their car back when no marketers wanted to touch the outlaw sport, then grew the brand, TapouT, into a $100-million industry.
"They were such good times doing what we were doing that when we look at that, it always puts a smile on my face," Caldwell said on Monday's edition of The MMA Hour.
