A "fan" ran onto the field and took off for about 70 yards (more than the team's leading rusher was able to muster) during this past Sunday's Chiefs game against the Vikings. The dude, as is always eventually the case, was tackled and taken off the field in handcuffs.
The team's mascot got in on the action to capture the trespasser. Check out the video on KMBC's site of the KC Wolf's effort to tackle the dude. It makes me laugh.
