To show how effective a commercial is, I personally had not heard SO many people refer to Wednesday as ‘Hump Day’ before this commercial debuted. IMHO, this is one of the best of Geico’s ‘Happier Than’ series.

AdWeek notes the following about the commercial:

“Uh-oh! Guess what day it is!” Advertising’s animal of the year wasn’t a dog, cat, pony, goat or hamster. It was Caleb the camel, the effusive ungulate who roams an office for Geico, gleefully badgering co-workers about the day of the week. Never has a motormouthed mammal been so endearing—in 30-second doses, anyway. So, what day is it? “It’s hump day,” a colleague finally admits. “Woo-woooo!” Caleb cries. (Folks who switch to Geico are “happier than a camel on Wednesday,” the brand’s folksy musical spokesmen explain at the end.)
