"JL Pipes" is the nickname for Captain Picard in reference to his beefy, manly, muscled, bold, and assured presence the few fortunate times TNG viewers are treated to a shirtless or even just sleeveless P-Stew. The "pipes" are his arms. His rippled, oily, throbbing arms. Robust, strapping, toned and turgid. Yes, indeed. JL Pipes.
