According to Reddit users, this is a real picture taken of two kids posing with Adam Savage and Jamie Hyneman in masks they had made for use in a Mythbusters segment about whether or not you could trick a security guard into thinking you were someone else like in a movie. My guess is yes, you can. *shivering* God, imagine if the two of them actually looked like that growing up. Did Adam and Jamie have to go to prom stag? CONFIRMED.
Thanks to andrew, who once had a lifelike mask of himself made, then posted it on a broomstick in his living room window and set the house on fire so everyone would think he was a total badass for just standing there in the flames while his face melted off. Man, I wish I'd thought of that.
