Double Trouble in the Panhandle

S4 E12: Booth and Brennan investigate the remains of conjoined twins found in a shallow grave in a remote desert area on the Texas-Oklahoma border. Back at the lab, the team determines the skeletal remains to be those of Jenny and Julie, who were jugglers in a traveling circus. Knowing there is no way the circus folk will talk to anyone outside their tight-knit clan, Brennan and Booth must infiltrate the circus community in order to find out more information about the twins' deaths. Honing Booth's Ranger knife-throwing skills, the duo goes undercover as knife-throwing act "Buck and Wanda Moosejaw." As they encounter a variety of suspects among the colorful circus crowd, including ringmaster Henry Simon (guest star Andy Richter), a rather raucous clan of clowns and a tempestuous strong man who may have been romantically involved with one of the twins, Booth and Brennan find the circus experience to be quite the spectacle.
