Why Hitting an Old TV Fixed It? [video]

Did anybody else who grew up in the 70s/80s have a little sister or brother who would be assigned the job of standing near the TV to smack it for the rest of us who were watching? Didn't even have to pay them, little kids just love smacking things, especially when they're given permission, and its an important job so they took pride in it.

Amidst all the slop videos nowadays, I find this format oddly refreshing.
