Who all seen da leprechaun? Where da gold at? All you gotta do is look up in da tree!
An oldie but goodie, "Who all seen the leprechaun" is the quintessential St. Patrick's Day meme, made popular by a local "news" story in mobile Alabama that went viral on youtube, in which a leprechaun gets loose in the 'hood and people flock from miles around to try and spot him in a tree. And find his gold, of course.
Happy Saint Patrick's day! Please drink responsibly.
