"Kick it loose for the moose"
One of my roomates in college was nicknamed "Moose", as he is a rather large fellow. Shortly after college, we took good jobs in a nearby big city and lived together as roomates. One Saturday, the phone rang. I answered it, and what sounded like a middle-aged woman was on the line. She asked for someone named Jim. I told her she had the wrong number, as no one named Jim lived in our apartment.

Shortly after I hung up, Moose came in the room and asked who was on the phone. I told him it was a wrong number, as the lady was asking for someone named Jim. Moose replied, "You idiot, I'm Jim. That was probably my mother on the phone." I had known Jim for years and never knew his first name!
