A video out of Germany has gone viral of some guy trying to tap a mini keg the old fashioned way . . . by using a mallet and spigot. He doesn't know what he's doing and hits it so hard that a torrent of beer shoots out of the keg and all over the room. It went viral a couple months ago, but it's making the rounds again.
(First he breaks a beer stein at :11 . . . and then the beer explosion happens at :49.)
