My dad tells this story of how one year when he was working security at a D.C. a guy on roller skates, dressed in a nun's habit rolled into the stadium with ballon bouquets. He wanted to skate into the arena and hand out helium balloons with bible messages inside. Pop the balloon get a scripture. LOL! Yeah, they surrounded him and wheeled him right out the door. I didn't get to see it though. :(
I also remember a guy here in Portland who had a freakin' long white beard, standing on the bus benches, hopping from bench to bench preaching a hellfire and damnation sermon at the top of his lungs at all the departing JWs after the session was over. Don't think he was an apostate though, just a crazy fundie.
Good stuff.
