If you didn’t actually watch the signing of the historic health care reform bill, you definitely heard about it or saw the video replay - and not for the reasons most people might think.

As he shook the President’s hand in historic Washington, D.C., while he was witness to the signing of a large piece of legislature, Vice President Joe Biden dropped the f-bomb. Oops. You can see and hear the comment in the video above - listen closely for it right around the 14-second mark.

Joe Biden’s comment (which was “This is a big f—-ing deal”) has now been immortalized on a T-shirt, which you can purchase on the official Barack Obama Web site. The shirt features the date of the signing of the bill and the letters “BFD” in big black type. This is not an April Fool’s joke (at least, we don’t think so), and sources say the slightly tongue-in-cheek T is well and truly backed by the Democratic National Committee.
