GEICO's 'Hump Day' commercial premiered in 2013, created by The Martin Agency, and starred Mike, a cheerful talking camel who wanders through an office on a Wednesday asking everyone what day it is. The ad became an instant internet favorite, and its catchphrase turned into a weekly ritual: people post the clip every Wednesday across social media, group chats and office channels. More than a decade later it still marks midweek on the calendar, one of the most quoted insurance ads ever made.
