Now you know Monero's dirtiest little secret - you're all prancing and hopping behind a lunatic. 
The thing about smart motherfuckers is they sound like crazy motherfuckers to dumb motherfuckers.
^This is so close to becoming my sig--this or a Nietzsche quotation.
I am adding it. Too good to pass up!
I first saw that one on a T-shirt years ago, and attributed to various sources since then. I like to pull it out for the dumb motherfuckers, from time to time
When I looking around to see where it came from most sources said the Walking Dead, but the comic book series not the TV show. The former dates back to 2003, so the T-shirt could be come from that. If there is an earlier source let me know and I will update my sig.
