We just keep a hood in each airplane. I have a pair of foggles too, some students prefer them over the Cone of Stupidity.
...you think of practical jokes like replacing hoods with the cones that the vet puts on your dog's neck, installing buttons labeled "Freeze" (a la Frasca Mentor) in the airplanes, or filling a co-worker's cubicle with balloons.
...to make night currency more interesting, you do things like soft field takeoffs and power-off 180s.
...you can predict, for each stage of each syllabus you teach, exactly which mistakes a student will make.
...you advise your students of exactly which mistakes they will make, and are not in the least surprised when they make them anyway.
