This is a vine video of some guy in Japan using an Airsoft gun to blast a Dr. Pepper can he taped to the wall, then running up to drink from it. Does that mask even have a hole for the mouth? Man, I want to move to Japan so bad and hang out with this guy. He gets me. So, what do you wanna do this weekend -- that Dr. Pepper thing with the guns and the masks? Cool. You're my best friend.
Keep going for the Vine video, sound is recommended for maximum WTFery.
Thanks to Vince, who agrees this is ridiculous and he should have used a grape Fanta.
