Mila Kunis and her “Bad Moms” co-star Christina Applegate stopped by The Late Show with James Corden on Monday night, where they participated in a game of Spill Your Guts or Fill Your Guts and made some unexpected confessions in the process.

During the eight-minute game, the two actresses and the host of the show were asked personal questions, and they had two possibilities: either answer truthfully or ingest something really disgusting and keep their secret.

Among the gross food items they had to eat if they refused to give an honest answer, there was ghost pepper hot sauce, grasshoppers, cow tongue, sardines, pickle juice, soy sauce and mayonnaise, clam juice, and calf brain.

We’re pretty sure nobody drools over those things, but the eating challenge was hilarious nonetheless, both due to the inappropriate queries and the three contestants’ comments and giggling.

The fun began with the very first question when James Corden asked Mila Kunis if Ashton Kutcher’s privates looked more like a “carrot stick or beer can.”

Well, the 32-year-old actress decided to spill her guts and describe her husband’s anatomy. She first answers carrot stick because she was thinking long and skinny, but then changes her answer saying

“Oh, beer can, beer can! I’m thinking short and stubby but no… like a Guinness.”

Had she refused to respond to James’ probing questions, she would have had to drink a dubiously colored glass of clam juice.

Mila has been very opened about her private life lately, as she also revealed that she and Kutcher started out as friends with benefits and talked a little bit about her previous relationship with Home Alone actor Macaulay Culkin.

In the next round of the eating game, Applegate gets off fairly lightly, but Kunis not so much as she ends up taking a bite from a cow’s tongue when asked to explain the plotline of last year’s “Jupiter Ascending.”

Corden, on the other hand, decides to make some revelations about a past encounter with the police, when he got in trouble because he called the U.K. version of 911 and yelled “Fire!” Then, on his second round, he got really embarrassed when asked who was his least favorite Carpool Karaoke partner and decided to eat the calf brains instead.
