Am I Really That Old?

So I saw a good deal in the paper on some movies and decided to go pick up a couple. One of them was "Dirty Dancing". I've always liked the movie, but never owned it and now it was only 3.99 so I thought for that I would go get it. As I waited in line VERY patiently. (How can there be 8 lanes and only 2 open?!) I got to the checkout and set the movie down to which the cashier said "That must be a good movie...a lot of people have bought it." For a moment I paused and I looked down to make sure I had the right movie and I am thinking to myself...how can you not know about Dirty Dancing??? Am I really that old? :)
