I'm thinking
a water safety course (I can explain the proper way to wade).

Let me know the date. I'll send a movie camera to one of the "pupils" so we
can capture this for future educational purposes - especially important
since this will be a one-time-only event. ;-)

Kinda like Wiley Coyote on stage doing his devil routine.
Bugs: "They loved it, they want an encore!"
Wiley as he floats toward the ceiling with little wings: "But I can
only do it once!"
