People who live in homes built in the 90s and earlier usually still have the plug for them. We hid ours behind a picture till we remodelled. If you visit someone in an older home, ask if they have the plug. It should be on the wall more than four feet up just as you're leaving the kitchen.
Sometimes people would buy an extra long cord (they snap into the receiver and base so swapping out was as easy as putting in a usb), and you could walk around the house clotheslining your siblings or stand in place and turn too much getting trapped in it. Fun times.
