Here is Aaron from Intervention. He is a mixed martial arts fighter who started acting in pornos, then got addicted to meth and masturbating while watching porn (great episode). The insert is his possible twin, actor Josh Brolin.
On the left is Jenni Pujols from Flipping Out (hilarious show), and on the right is her identical twin Julia Louis Dreyfus.
Here we have Sig Hansen from The Deadliest Catch, and his doppelganger Bobby Fischer, one of the greatest chess players of all time.
I usually stick to reality shows for the celebrity look a likes, but there were a couple from the sports world that I couldn't ignore:
Jim Carrey is coaching the Dallas Mavericks???!?
Little Wiley Wiggins from Dazed and Confused grew up to be San Fransisco Giants pitcher Tim Lincecom!
Stay tuned for more......
