Tonight when I picked up a plate from a table, I knocked over the salt shaker. I made a joke about being clumsy as the guy quickly set it up right, and I was turning to go when he said, "Wait! Throw some over your shoulder!"
I looked at my hands, one which had his dinner plate and the other which held a tray and several menus. I wanted to ask him to wait a minute while I grew a third arm for that, but instead of I laughed and said, "Why don't you do it for me?"
He looked confused.
