With all due respect to the honorable mfumbesi, I regret to state that it has been found desirable (CF 1809:2987:234 sub. BX9345 Ref. Gal. Con. Cod. Dir.) for choices of new existential modalities to be governed by the Equal Opportunities Act for Organic Manifestations of Physical Law.
My subcommittee's investigative report, undertaken over the course of two millenia and comprising seven tenths of the galactic arc, taken contiguously, shows that out of the six varieties of simple machine, two (lever and wheel) are overwhelmingly represented in locomotive modalities of sample populations and four (inclined plane, wedge, pulley and screw) are almost entirely neglected. I am sure that all will agree that this display of favoritism is entirely repugnant and contrary to our noblest and most democratic ideals.
The so-called "leg," "wing" or "fin" (lever), and the "flagellum" (wheel), are therefore undesirable for consideration in selecting the locomotive means for the animal in question. Since the
wedge and
screw have already been considered and found somewhat wanting, I propose that the target animal use the pulley as its primary means of locomotion.
