James Corden Forces Mila Kunis to Reveal Details About Ashton Kutcher's Penis

James Corden has figured out the secret to getting even the most private A-list celebrities to reveal their deepest, darkest secrets on national television: threatening to make them consume the world's most disgusting foods and drinks. The late-night host did just that when he had Bad Moms costars Mila Kunis and Christina Applegate play the Spill Your Guts game when they stopped by on Monday night. When faced with drinking some clam juice, Mila chose to say whether husband Ashton Kutcher's manhood is more like a "carrot stick" or a "beer can." "I have to have one or the other?" she laughed. "Carrot stick. Beer cans are short. Oh, beer can, beer can . . . I was thinking short and stubby and long and thin. But like a Guinness." Although she avoided that round, the former That '70s Show star did end up eating cow tongue (she couldn't describe what Jupiter Ascending was about, but to be fair, can anyone?).
