Jon Hamm, the star of the hit series 'Mad Men,' has quickly become one of Hollywood's favourite celebrities. First comes fame, then comes nicknames, right? Fans of Hamm have graciously decided to nickname the star's genitalia—Meet the "Hammaconda."

During a guest appearance on 'The Late Late Show with James Corden,' Hamm played a game of Spill Your Guts or Fill Your Guts. This segment consists of celebrities choosing to either share secrets or eat disgusting food. After a few rounds of daring each other to drink hot dog smoothies and consume shots of hot sauce, the REAL question hit the stage. 

Corden gave Hamm the choice: Eat pieces of a bull's penis or reveal how big the "Hammaconda" is. After much deliberation and tons of cheering from the audience, Hamm decided to remain private and eat the gross meat!
