Ramblings and Puzzles

Here's one from the Art of Problem Solving forums, that I created a little less than two years ago (the problem, not the forum):

The Grammar Corporation was at it again. They acted like they were still in diapers! They were trying to tell me how to spell stuff. For example, they told me to spell "yen" with a capital Y! I mean, it's bad enough that they managed to anger many a client, but this was newfangled of them. "Give us a call back," they said right before hanging up. "We'll see if we can adapt your profile to a pay-per-usage model." Well, that certainly gave me swollen glands. I'm never using their service again.
