XKCD Web Comic #951: Working (described)

A web comic of romance, sarcasm, math, and language.

Scene: Drawing of a stick figure next to a gas pump, filling up the gas tank of a car. Another stick figure with a ponytail is standing on the other side of the gas pump, pointing away.

“Why are you going here?–Gas is ten cents a gallon cheaper at the station five minutes that way.

“Because a penny saved is a penny earned.”

Caption: If you spend nine minutes of your time to save a dollar, you’re working for less than minimum wage.

Hover text: And if you drive a typical car more than a mile out of your way for each penny you save on the per-gallon price, it doesn’t matter how worthless your time is to you–the gas to get you there and back costs more than you save.
