On Saturday, Joe Biden did something no one else has ever done before: He fell off a bicycle. It happens! But Biden happens to be the president of the United States and the fall happened to occur right in front of a press pool, meaning there was clear video of the incident. So of course there was a lot of dragging and chuckling and what have you about a guy who’s already very gaffe-prone. Naturally his former presidential rival, the guy he beat, got in on the fun.
