It's unclear where or exactly when this video was recorded, but the star of it is upset. Pacing back and forth in his half-empty section behind goal, he suddenly decides to unleash his fury on a seat, unaware that the seat is prepared to fight back.
His foot gets stuck and after a second of holding the awkward position, he goes flying backwards down several rows of empty seats. The man gets up and trudges back to his row a little embarrassed, a little more angry and a little more aware that kicking inanimate objects can backfire.
