That reminded me of this great article that I read back in my Sociology 131 class in college...
It was "Body Ritual among the Nacirema:"

I will warn you ahead of time that this is not a short read, set aside 15 min to read it... Also take the mindset of a student in Sociology 131, this is the first article we were given after the speak on opening your mind to other cultures.
If you have the patience to read it all and think about it, and get it, you will be rewarded I think...
