I directed a High School production of Twelve Angry Men. For purposes of the play, I needed two identical, unusual-looking switchblades.
I got them. Never mind how (since they are illegal in the US), that is another story.
Anyhow, the show went off without a hitch. We were invited to a competition and performed a scene from the play. Once they were done, I took the knives back immediately; I didn’t think it was a good idea to let my students show them off the the other 100’s of students there. Of course, the knives were blunted, but still…
Anyhow, skip ahead 3 months - I fly home (from NY to KC) for the holidays. I am flying back and the security guard in KC decides the make my carry-on bag the example. She does that chemical-wipe test for explosives, then asks me to empty it. I begin to act indignant, upset, “I’m late for my flight!”, etc…
She finishes up, then the guy at the X-Ray says he wants to run in through again. And again. And again. I am really upset now - making quite a scene. He has emptied everything out of my bag (folders, student papers, essays, tests, magazines, etc) and made a mess of it, yet he keeps on flipping the empty bag over and over, peering at it and thrusting his hands into the pockets.
I finally ask him what he is looking for and he says, “I see the shadow of a pocket knife.”
I think, “Oh, the switchblade made an impression in the leather - that must be what he sees!” and volunteer to show him. I open the zipper pocket deeeeep inside (you know, the one I chose to put the knife in to keep it away from my students!) and… see where I am going?
I pull the fully open, wicked looking switch-blade out of the bag. “Heh,” I say. “You’re not going to believe this!”
They did not think it was funny.
