The Man in the Mud

A young couple goes skinny-dipping in a spring, but their moment of fun is ruined when they uncover a skeleton in the mud. Brennan and Booth are called to investigate and find that the skeleton is that of Tripp Goddard, a motorcycle racer who recently won the Super Grand Prix. The first suspect is Danny Fitz, the race's second-place finisher. However, though Booth and Brennan think they have the case wrapped up, another crash claims another victim in suspicious circumstances. Meanwhile, Dr. Sweets has Brennan and Booth go with him on a double-date in order to get them into another social setting together where they have to interact away from a case.
