While Calif. Gov. Arnold Schwarzenegger's tweet that he'd met with Sen. Barbara BoxerBarbara BoxerThis week: Shutdown deadline looms over Congress Senators seek to boost women in international forces Overnight Energy: Senate approves Flint aid | Union chief backs Dakota pipeline MORE (D) is interesting enough, he included a TwitPic that is maybe more intriguing.

More importantly would be the extra leg in the picture, making us wonder whose unfortunate knee is in the brace.
