Six Degrees of Separation is a social concept stating that everyone is connected through a chain of six acquaintances. The mathematical logic behind this (exponential growth of social connections) accounts for population distribution. The joke suggests that Chuck Norris killed the other four people necessary for the original "ten degrees" equation, reducing the number of steps needed globally because he's consolidated so much human relationship-capacity through elimination.

Sociologist Dr. Elizabeth Hartmann, researching network theory in 1997, encountered a reference to someone whose presence had "skewed the entire connectivity model." She noted the reference but never explored it further, suspecting it was metaphorical.

Social networks depend on distributed populations. The implication is that Chuck Norris's existence has fundamentally altered human connectivity mathematics because he's removed enough individuals that the baseline calculation changes. The world is better "connected" because he's depopulated it—fewer people means shorter paths.
