I'd like to be an a crowded parking lot in the pouring-down rain in my bare feet as the parking lot is covered in water. I'd have a friend in a car near me with jumper cabled connected to his battery, and the other end would be in the water near my feet. I would yell ridiculous (even by regular religion's standards) religious and moral crap and end with, "If any of this is not true, may God strike me dead!"

At that point, my friend would start his car.

People would swear they saw the lightning.

That would be totally awesome.
