Steelers fan celebrates too early

Every diehard sports fan knows: Don't celebrate a victory until the clock runs out..and even then, wait a few seconds.

This Pittsburgh Steelers fan forgot that rule and started a victory dance in the San Diego Chargers v Kansas City Chiefs.

The Chiefs were about to attempt a potentially match-winning field goal that would have sent the Steelers into the postseason.

The fan obviously thought the kick was unmissable as he began his extended dance in front of the TV and others who weren't as keen for the Chiefs to get the points.

But the shot missed and the Chargers won, sending them to the playoffs in the spot the Steelers would have filled.

The man stops dancing while the others in the room suddenly find some moves of their own.
