Wanna feel old? It was just eight hundred years ago that the first season of The Ultimate Fighter graced our television screens. And castmember Mike Swick just posted a “then and now” comparison on Twitter.

If you’ll recall, Swick shared screentime with the likes of Forrest Griffin and Stephan Bonnar – with their fight at the finale ensuring the success of the franchise, and the sport, forevermore.

There was also dudes like Bobby Southworth, Lodune Sincaid… and how could anyone forget Diego Sanchez and Chris Leben?

Anyhoo, time is a bitch, so some of these castmates look nothing like fighters nowadays. Which is just as well.
