Even funnier is the Kids React episode they did on Rotary Phones.
When we had our antique shop, I would get a big kick out of the kids that would come in with their parents and when they would see an old rotary phone, they would ask, "What is that?" When they heard it was a phone, they would always ask, "How do you dial it?"
We used to have a beautiful old floor model tube radio from the forties sitting up by the counter. One day, a teen-aged girl came in and was looking at it - walking all around it, really studying it. Finally she looked up at me and said, "What is that?"
It really does make you feel old.
