In moviemaking, there is a great prank often played on the newbie on the production crew. More often than not, this is the Production Assistant, fresh out of school, who knows next to nothing about filmmaking. The camera crew calls the PA in with an URGENT errand. “Quick, drive to the rental house to get us a large-sized bag of F/STOPS, and hurry!” The PA runs desperately to the rental house and demands a bag of f/stops, at which point the staff bursts out laughing. (Of course, f/stops are a setting on a lens, and certainly nothing you can put in a bag. There inlies the comedy, you see). It’s a great prank for knocking a cocky PA down a couple of pegs. So, if someone asks you to get a bag of f/stops, tell them it’s right next to the box of spinners (swizzle sticks!).
