The Locker Answering Machine I totally remember my locker message machine. I wanted one so bad for my birthday. My parents bought me one, and I stuck it to the inside of my locker. It had a stretchy cord and a little receiver that stuck to the inside door just behind the air vents. Friends could blow the disk-shaped whistle and the recorder would start. No one ever left me a message because it was really a dumb idea, but all my friends thought it was cool!
