I was up on Glacier National Park and wanted to go down a path to see something or other. On a boulder was a mountain goat, which I did not see but to which my wife drew my attention ("Psst! Hey, dummy! On your left!") Every time I took one step past that goat it would clatter its hooves and in general let me know I wasn't to go further. I tried it a couple of times and then backed up outa there, eyed by the goat until I backed around a corner out of sight.

My wife thought it was a pretty funny thing to see me intimidated by a mountain goat.

Then there was the time in Custer State Park in South Dakota when we were in the car, watching a VERY large and VERY male bison amble directly at us. I was fascinated, until my wife said, in a rather loud voice, "I said, MOVE THE GODDAMNED CAR!" Bison amble wherever they want to....
