The other night I was looking at my copy of the 2004 edition of First Aid for USMLE Step 1 and noticed a couple of positive reviews for the book. It said they were "online reviews", so I assume they came from the Amazon website. I noticed that one of them ended with -A reader from Arlen, Texas. The funny thing is there is no town of Arlen, Texas, it is a fictional town from the cartoon King of the Hill. So I wonder if the authors of First Aid did it as a joke, or are they just clueless.
