I had an old microwave or speaker magnet on the wall of my schoolbus, papers regarding riders stuck to it with a set of toenail clippers clamping them down by their attraction to the magnet.
“Mt. Green, is that a set of toenail clippers up there?
“Yes, it is.”
“Of course it is,” and the student had no further question.
(Being (falsely, of course) considered insane has its benefits.)
