When a non-OEM part installed during their last starbase visit leaves the Enterprise by the side of the road, the crew looks for someone to blame. But when the crew's investigation moves a patsy into their crosshairs, it turns out that he's guilty of something totally unrelated. Is an elephant's foot the most unlucky foot? When is it appropriate to show your ass in court? Do you have to pay extra for dialogue? It's the episode that's all ends, and no means.
