A sexual feat that requires the aid of a trustworthy pilot, oil, feathers, and a
horny countrymen with nothing better to do. A
male covers himself in oil, then proceeds to roll around in a pile of feathers. If done correctly, he'll almost appear to be a
bird. The male then straps himself into a World
War 1 open cockpit
bi-plane. At exactly 9,865
feet, the male jumps out of the plane, without a parachute, plummeting towards the ground at terminal velocity. During this
time the male becomes aroused, then makes his penis perpendicular to the ground, and then finally flaps his arms imitating a bird like motion before smashing "dick first" into the ground. This feat was first done by the famous Oklahoma resident Harry Sack in 1948 thus, giving the feat the name "1948 Oklahoma Pile Driver". This same feat can be done to a woman however, you would also need to hire a skillful mathematician in order to figure out the exact timing to
jump from the aircraft.
