I know what you’re probably thinking, “this is from Joan, its gotta be stupid!”  Well let me assure, it is, and it will not disappoint.  As someone who has NO IDEA how to navigate an office etiquette, I found this series to be both informative, and hilarious.  So lower your standards of humor, and enjoy this NSFW (but about work) series!
