This item from xkcd by Randall Munroe is titled Kolmogorov Directions. What does Kolmogorov have to do with maps? Probably his mathematical work regarding topology, or the relationship of the location of things to one another.
The "title-text" at the actual webcomic has an additional GPS-related joke in it:
People get really grumpy when they realize you're giving them directions for how to go to the store and buy a GPS.
