I could do without the song, but I firmly believe the world would be a better place if everyone took a moment now and then to dance as if they were riding a horse while really having to pee. Apparently someone at Zynga agrees.
If you're playing Farmville 2, keep a close eye on your avatar when he or she levels up -- they might be farming Gangnam style too. The fine folks over at The Scoop witnessed the dance sensation sweeping the plantation, which apparently happens to a random selection of players when they reach the next level in Zynga's latest farming simulator.
I was pondering retiring my farm, but I can't now -- not until I've danced the forbidden dance.
