They were standing waiting for the signal to take off barrel bags, and joe was switching hands... he accidentally hit the trigger. It was hilarious cause he didn't expect that to happen.
Oh then 5 seconds later he got shot in the hand.
I had a game similar to that once. 3...2...1.. go! I run to my bunker... fall on my ***. A pod busts open and I lose that paint. Get to my bunker and start shooting. My barrel bag was on.
