When we traveled to Japan last month for my fight with Anthony Pettis (which did not go so well), we did a series of video blogs leading up to the fight and then everything that happened after. Well, we may have been slightly influenced by Tyler Durden in the Fight Club movie, and cut a few still shots into the footage. We did it hoping someone would pick up on it, but no one caught onto it! The first person to figure out what the image is will win some GammaLabs PTF. You can post a comment below, tweet to me, or leave me a comment on facebook!
Few hints:
1) The image you are looking for is is one of these videos.
2) The image is more than 1 frame, but comes and goes very quickly.
3) The image is something from my childhood (and not pornographic like in fight club)

Good luck!
