Before POGs became collectible items printed with our favorite ’90s pop culture characters, they were just simple discs found inside bottle caps.

On this episode of The List Show, Mental Floss host Justin Dodd is sharing the origin stories behind 25 popular acronyms and initialisms, many of which you may not have realized actually stood for anything at all. Geico, for example, isn’t a word that insurance providers made up to match their spokes-gecko; it’s an acronym for Government Employees Insurance Co., made up to match the company’s original target demographic (government employees). And since LED stands for light-emitting diode, the phrase LED light is rather redundant.
