Just when you think you've seen it all on an amateur ball field...

[SE Minnestoa Re]

I had a streaker at a college softball game a number of years ago. He came over the first base dugout, ran across the field and jumped over the outfield fence (short, portable fence; he wasn't that athletic). The best part was when he went by the centerfielder, she pointed at his attributes and laughed.

An arrest took place shortly after.
