Chris Sullivan has a new story to tell about life before This Is Us, and it caught Sterling K. Brown and Mandy Moore off guard. On the trio's That Was Us podcast, Sullivan revealed that he was the voice behind GEICO's talking camel in the 2013 Hump Day commercial, leaving both of his former co-stars speechless.
The reveal landed because the ad became a pop-culture phenomenon the moment it debuted in 2013. The camel, named Caleb, wandered through an office asking, 'Guess what day it is?' before turning Wednesday into a joke everyone recognized, a line that spread far beyond TV and into everyday conversation.
That is the part Brown and Moore thought they already knew. After six seasons together on This Is Us, Sullivan had become a familiar face to millions of viewers, but his voice had been hiding in one of GEICO's most recognizable ads all along. The commercial was created by The Martin Agency, and its success helped make Hump Day shorthand for midweek relief, with memes, parodies and endless Wednesday references keeping it alive long after the spot first ran.
The surprise is also the story's biggest wrinkle: Sullivan was not just another castmate with a few jobs on the side. He had one of the most recognizable ad voices of the last decade, and Brown and Moore did not know it until the podcast conversation opened the door. The show gave them six seasons together to trade stories, yet this credit stayed buried until now.
What remains unanswered is the simplest part of all: how Sullivan got the camel job in the first place. The reveal answered who was inside the voice, and why the ad still sticks in people's heads, but not how he was chosen to deliver one of the most replayed lines in modern advertising. That gap is now part of the story, too.
