@stavvers So, I did some rough math based off the initial post mentioning a 4000 mile fart-powered dick travel distance.
A projectile travelling 4000 miles on a ballistic curve with no additional propulsion needs to be launched at a velocity of 198 miles/s, or 318.6km/s.
Assuming the dick is erect (makes for a more optimal projectile), an average human penis length of 13.2cm and average circumference of 11.66cm (source: wikipedia) we can calculate the weight of the dick by using the average density of the human body (0.98g/cm3) to get the a mass of 139.9g.
An object with a mass of 139.9g travelling at 318600m/s has a kinetic energy of roughly 7.12GJ, which (again according to wikipedia) is somewhere between a Boeing 767 and and Airbus A380 at cruising speed.
It is therefore safe to say that any animal impacted by the dick shortly after launch, would suffer complete destruction.
