Megan Fox has an interesting condition called club thumb (or in not so layman's terms, brachydactyly), which is an inherited generic trait.

Or, if you ask the tabloids, her thumbs are actually toes.

Fox is so self-conscious of her thumbs that she's said to have even used a thumb double for a Motorola ad that aired during the 2010 Super Bowl.

But her condition isn't that uncommon -- at least 4 percent of the population has so-called "stubby thumb."
