Barack Obama's 50th Birthday: A Look At The President Then & Now (PHOTOS)

Happy birthday, Mr. President!

Barack Obama might be turning the big 5-0 on Thursday, but as far as we're concerned the Commander-in-Chief is 50 years young.

Despite his increasingly-gray hair and the "dents and dings in the fender" (is that a dad phrase or what?), the president swims, bikes, takes time to joke around and to top it all off, his wife still thinks he's cute.

Even at 50, Barry's still the youngest candidate heading into the 2012 presidential elections!

So to celebrate POTUS' mid-century milestone, take a look at Obama then and now, from his childhood in Indonesia and Hawaii to today in the White House, with the child definitely still inside of him.
