From what we can tell by the info via the uploader, this was from after Friday’s Cardinals-Cubs game.

Well my first experience at a Chicago Cubs game is one that won’t be forgotten! After winning against the cardinals 7-0 this drunk fan wasn’t going down with out a fight. Little did he know he’d be fighting himself, and going down pretty hard!
Hard? How did that guy even get up after snapping his head off the concrete like that? Nevermind the booze he had been pounding, how in the hell did he even know what guy he was supposed to be fighting?
Notice he runs into the building after getting up.
*Of course the Cardinals rebounded on Saturday and Sunday by outscoring the Cubs 10-1.
