A Mathematical Approach To Help Reduce Urinal Protocol Vulnerability

Urinal Protocol Vulnerability

xkcd takes a mathematical approach to help reduce Urinal Protocol Vulnerability and prevent awkwardness while peeing in public restrooms.

When a guy goes into the bathroom, which urinal does he pick? Most guys are familiar with the International Choice of Urinal Protocol. It’s discussed at length elsewhere, but the basic premise is that the first guy picks an end urinal, and every subsequent guy chooses the urinal which puts him furthest from anyone else peeing. At least one buffer urinal is required between any two guys or Awkwardness ensues.
