A bartender wonders about the origin of the term jockey box. In his world, a jockey box is a metal container for ice. However, in some parts of the western U.S., a jockey box is the glove compartment of a car, and much earlier, the term referred to boxes attached to the side of chuck wagons for holding feed or water. The caller also shares another bit of bartending slang, the so-called mat shot or Matt Dillon. It’s a glass of whatever liquor collects on the rubber mat on the bar, which some enterprising patrons order as a prank or a test of a strong stomach. This is part of a complete episode.
