If you asked a young person today what a rotary phone is, they'd probably just look at you with glassed-over eyes, having no idea what you were talking about.

A listener sent in this video above and its worth taking the time to watch, if for nothing else to laugh that someone actual made a tutorial on how to use a rotary phone.

The video will take you on a walk down memory lane and give you a laugh for the day. Enjoy.
