I like gags like this.  Even when I had blood clots in my leg and had to walk from the car to the emergency room entrance, I didn’t circle looking for something close.

I really enjoy Bill Bryson’s take on it.  In at least two of his books he mentions a family friend who drives a mile to a gym to run on a treadmill.  When asked why she didn’t run to the gym and back and do two miles less on the treadmill, she said that the treadmill keeps track of her calories burned, duh!
