Very, very clever MIT. It JUST struck me. The Fleming cannon is non - RF'able, according to the Interhouse Committee Resolutions at Caltech. That means it's not prankable. The LITERAL definition of RF is "Rat Fuck," when to prank someone, you would catch a rat, dip it in LN2, and then smash it in someone's room. The smell is enough to knock your socks off! And you cannot find all the pieces ever, so it lingers for months. Putting a gigantic brass rat on there is pretty hilarious. You've rat fucked it, and depending on how dirty your mind is, in more than one way. Well played.
