OK, this isn't really a joke, but I did find it amusing.
I was driving the other day, glancing at my GPS from time to time.
At one point, to get from one road to the next, I had to go along a short stretch that went between the two roads.
Apparently, my GPS didn't know what to call that little stretch. When I glanced at the display, it said "Driving on road".
I thought, "That's nice to know". I wonder, if I took a hard right here, would it change to "Driving on sidewalk"?
