Back in the day, when all phones had cords, my mother would walk around the house stretching the cord and generally annoying everyone in the house and regularly ripping the cord out of the phone rendering it useless until my grandfather could fix it.
One day grandpa showed up and had this little wooden thingy he made in his shop. He attached the thingy to the phone cord about two feet from the phone and when mom tried to stretch it around a corner the thingy would catch and stop it from being stretched too far. Grandpa was a genius.
