Want to feel old in a hurry? Go to a fast food place. Any will do. The younger the workers, the better. Have your meal ring up to $19.99. Make a comment about bursting into a Prince song. Get a blank stare. Tell them it was probably before their time. And then hear them tell you that their mom likes that song. See? Instant old fart. This may or may not have happened to me in the past few weeks.
