Always on the lookout for new ways to motivate graduate students to get their work finished, I took note of this handy item while flipping through the Fisher catalogue in search of a flammables cabinet for the lab.

The shoe, which is conveniently located at butt-height, would need to be on a spring, and it would be better if the gun were pointed outward and on a remote control turret or lack-of-motion sensor, but perhaps it could do the job just by its menacing presence.

(Note: This is a forensic evidence cabinet taken out of context for comedic effect. Never point a gun at anyone. No graduate students were harmed in the writing of this joke post.)
