Video goodness for you

Then I found this post about it on a Colts message board:

The year was 1971 and our beloved Colts were playing a home game (which at that time was in Baltimore) against the Miami Dolphins. In between plays, as the Colts defense waited for the Miami offense to come to the line, a thirty-something year old fan, drunk and disorderly, ran out on to the field and grabbed the ball. Of the 22 players on the field at the time, 21 of them just stood there, awestruck, but one man, middle linebacker number 36, Mike Curtis, saw the opportunity to get another good lick in before the end of the game.
The fan had a hold of the game ball for less than two seconds before Curtis laid him out in a scene reminescent of the movie "The Waterboy." The fan was fined, taken to jail, and then to the hospital. Mike "The Animal" Curtis, who was known for chewing the bars off of his facemask and eating window panes from the team bus, simply stated, "He shouldn't have been on the field."
Curtis played 12 years with the Colts and appeared in 4 Pro Bowls.
