We owe it all to Fisher-Price®.
Our son received the "Little People® Fun Sounds Garage™" when he was very young. The toy features numerous buttons to play different "garage" sounds - air wrenches, gas pumps, a cash register (cha-ching!) and a telephone.
He loved pressing the buttons (actually, he's still a button pusher), but his particular favorite was the telephone, located on the garage's third level.
One day the garage's owner (we call him Mecha-Nick - that's him standing atop the garage in the picture) was distracted from fixing a car by the telephone's near-constant ringing.
Dropping his wrench and racing up to the top of the garage, Nick picked up the phone and answered, "Three Story Garage, how can I help you?"
