It's not easy to bust out the moves that the pros do and on Monday (September 24), Bill Nye suffered an injury during his "Dancing with the Stars" performance.

A rep for ABC tells Gossip Cop that he's "currently seeking medical attention" for a knee injury sustained when he tripped and fell at the end of his routine.

Unfortunately, insult was added to injury as The Science Guy received a paltry score of 17, the lowest of the evening.

There was some good news from the judges though. Check out Bill's moves and his fall in the player below.
