Should have known this, since most of what I know

[Markekohut]

Comes from Pynchon. Halfwit's joke. 

From a Gun violence article ( in Wikipedia)

Deaths from gun violence( and other rare acts of crime) tend to follow
a Poisson distribution when statistically mapped. 

Wikipedia also learned me that one of the first uses of Poisson distribution analysis was
Some guy asked to find out the pattern of deaths of Prussian soldiers kicked in the head
by a horse. 

Pynchon's genius at illuminating the world is stronger than a Poisson distribution.
