Technologically Obsolete Phrases

Think Pink blogged about her daughter not knowing what a bottle cap was. It got me thinking about obsolete images and phrases that won't be part of my children's world the way they were part of mine. And, then I started thinking that it would be kind of cool to make a list of phrases that just don't work anymore, unless you're old enough to remember that technology.

I can think of two things:

Coke bottle-bottom glasses
broken record (always a classic)

What about you?
