The Klingon martial arts program was a holoprogram available on USS Voyager. Sometime prior to the Voth's intrusion on Voyager in 2373, Tom Paris planned for him and B'Elanna Torres to spend time playing this program, but she managed to avoid the encounter. He then bet her that an anodyne relay was the cause of an engineering malfunction, while she favored a plasma conduit; if he were right, he would choose the activity he wanted them to do together. When he was proven to be correct, he told her to meet him in "Holodeck two, Klingon martial arts program, no getting out of it this time", adding an instruction to "BYOB", or "Bring your own bat'leth".
