I think the key to that "10 things I've done that you probably haven't" meme is to be as specific as possible. For example, many of us might have had flashbacks of The Wizard of Oz... but how many of us had said flashbacks in Bulgaria? Several of us have probably ridden unicycles, but how many of us were in Pakistan wearing red sweaters and yellow bloomers when we did it?
I haven't done either of those things. I'm sort of sad.
