While parked for a moment, I was watching a guy mowing his lawn. Also in the lawn was his very large Saint Bernard. That dog did not even care; when the guy came close with the lawnmower, he had to stop and ask the dog to move; the look on the dog's face (very much "sigh, whatever") as it moved a whole 5 feet away, and the mower laughing hysterically, both MMD.
