I kind of love Mary-Kate and Ashley Olsen. I kind of hate them too.
That being said, this just cracks me up.
A MSNBC article reveals that MK and Ashley's weird "smiles" are the result of saying the word "prune" each time they pose. Literally. Prune.
"Another source close to the Olsens could not confirm the precise word they use as their smile trigger, but says their smiles are keys to their identity. They do care about their smiles though. Mary-Kate has slightly thinner lips and more of a playful grin, while Ashley tends to go for a full-on pout. It has been the obvious way to tell them apart for years.”
Is this supposed to be a joke? Next time you're in a photo-opt, just say PRUNE!
