Hmmm... runners on first and second and nobody out... hitter pops up and is automatically out via the Infield Fly Rule... ball falls untouched in front of the shortstop... the runner on first, confused, starts running and passes the runner standing on second... so the runner on first is out for passing a runner in front of him... runner on second panics and starts running to third, and runs into the ball before the shortstop can play it... third out.
How’s that?
You beat me (I went to check Rule 7!)
