Weird History is ordering a Double Double telling you the History of In-n-Out Burger. The famous burger chain was founded by Harry and Esther Snyder. Harry first visited a local market to buy fresh ingredients for his 10-square-foot-wide hamburger stand. From there, In-n-Out has exploded in the West and Southwest with a rabid, almost cult-like following. You're gonna want this video Animal-Style, so sit back, relax, and enjoy.
