This one would take two people to work smoothly, but would definitely be memorable for all in attendance.
About 1 minute before the song starts for the afternoon session the following happens:
Conspirator #1 sits within 100-200 feet of the stage wearing typical MS/Elder apparel. He has the electronic controls set up inside his shoes (ideally) or at minimum held in his lap underneath a jacket.
Conspirator #2 walks into the auditorium casually carrying a picnic bag which actually contains a fairly inexpensive radio-controlled helicopter. He approaches a row of seats near the stage with a good line of sight to Conspirator #1. He sets the RC helicopter on an empty seat and immediately heads for an exit, never to be seen again.
Conspirator #1 is at the ready the whole time. If Joe Attendant notices the helicopter right off the bat and makes a move towards it, Conspirator #1 springs into action. (Or at least his fingertips do.) The helicopter flies up to the top of the speakers on a pole, well out of anyone's reach. Hopefully though, it goes relatively unnoticed. The 'copter stays up there until the best talk to disrupt begins. (Preferably a Bethel speaker or the dreaded "Keynote Address".) Then the copter is flown down to the stage, making one or two passes of the podium before settling down conspicuously on the front part of the stage. If attendants rush the platform to remove it, the copter flies back up to the top of the speakers and waits. If the attendants choose to ignore it, it will lift up and down on the front of the stage every minute or two. Just imagine how interesting this talk would be to all the kids in attendance! The attendants are damned if they do, damned if they don't do anything about it.
