The incident was all caught on tape, and is scorching online as one of the most-searched viral videos of the day.

The damage to the structure caused the NFL's Minnesota Vikings to push their Sunday game against the New York Giants to Detroit's Ford Field on Monday, as the Metrodome is not expected to be back in working order until Wednesday.
