This Is Us Star Reveals Secret Voice Role in Famous Commercial

'This Is Us' star Chris Sullivan surprised co-stars Sterling K. Brown and Mandy Moore on their podcast by revealing he voiced the talking camel in GEICO's viral "Hump Day" commercial from 2013. The duo was stunned to learn that a familiar character they had heard millions of times belonged to one of their former colleagues, leaving them speechless during an episode of That Was Us. Sullivan did not disclose this detail publicly until now, noting that the role is particularly surprising because the voice became so iconic in pop culture without many people knowing who performed it. The 2013 advertisement created a lasting cultural impact with its catchy question and enthusiastic celebration of Wednesday when answered correctly.
