Don't run onto a court, ice rink, baseball diamond or football field during a game.

In the past, athletes have been attacked by crazy fans who rush a court during a contest.

While no one was hurt in Game 5 of the championship series of the PBA Philippine Cup Finals between Magnolia and San Miguel, a patron dressed as Spider-Man decided to rush the court.

I have to admit, I laughed when the shocked announcer yells, "Oooh, Spider-Man! Who is that?"
