I stopped off at King Soopers on my way in to work to pay a couple of bills and pick up fluids for my stuffy head. On the way in the door I was passed by a tall, skinny, grey-haired Lurch looking guy with glasses who was on his way out. Since he looked a bit odd I watched him for a second as my door was cycling open. He took three steps, stopped and said, apparently to the parking lot at large, "Bong!"
I walked on in without looking back.
