I'm somewhat embarrassed to say that 13-year-old me was wondering why he’d never heard of the Nacirema before. Until we discussed in class the next day, I didn't realize it was "American" spelled backwards.
Edit: Actually, I think the particular article we read in school was "The Mysterious Fall of the Nacirema". Thank you to UncleSlacky for posting it elsewhere in this thread, I didn't realize there was more than one.

Ouch.
