The other day while perusing photos, I came across a shot of an attractive blond who reminded me of a young Michelle Pfeiffer. Then I read the caption. Mary-Kate Olsen? Bahwah? Now, I’ve always fallen into the "Olsens look like lorises" camp. Or Gelflings. Or food-deprived troll dolls. But this, this insane similarity made me doubt all my long-held and strongly-felt beliefs on celebrity twinhood. How could this be? Has the world gone mad?

Short answer: Yes. Long answer: Hell, yes. Sure, all stars have their obvious twinsies. Angelina Jolie and Megan Fox’s similarities have been so exhaustively dissected that even your grandma could tell you, “Oh, honey, that Transformers girl is just trying to steal Angie’s look.”

But the more you look around, the more you realize that unlikely (and downright odd) celebrity twins are everywhere. And these weird-alikes just keep getting weirder.

Jessica Alba and Elizabeth Berkley

Uncanny, no? So much so that Jessica may want to have a long talk with her agent about her career trajectory.

Lindsay Lohan and Zac Efron

Quick, someone take away Zac’s car keys and check his pockets. What? You can never be too careful.

Paris Hilton and Big Bird

If only Paris had followed Big Yellow’s example. Instead, she fell in with his ne’er-do-well cousin, Orange Jumpsuit Bird.

Elisabeth Hasselbeck and Mr. Fantastic

If Rosie had known about Elisabeth’s secret superpower, she surely would have taken the opportunity to give her the on-air neck wringing she so rightly deserved.

Britney Spears and Bat Boy

This one is too easy. In fact, I almost feel bad posting it. Almost.
