Watch: Jon Hamm Asked to Dish About His... 'Hammaconda'

Jon Hamm appeared on the "Late Late Show" with host James Corden. The duo played a game of "Spill Your Guys or Fill Your Guts" – it's like the classic game of truth or dear meets "Fear Factor." If you don't answer a question, you're forced to eat some truly gnarly food.

In the "Mad Men" star's case, it was either open up about his "hammaconda" (ahem!) or eat a bowl full of dried bull penis! Hmmm....

Watch the hilarious clip below and find out if Hamm ate penis or talked penis.
