Top 10 Funniest Spill Your Guts or Fill Your Guts Moments

Whoever said breakfast was the most important meal of the day probably didn't have this kind of spread in mind. As part of her Witness World Wide live stream, Katy Perry is woken up to delicacies such as cow tongue and bird saliva, and her reaction to each dish is priceless. Faced with a thousand-year-old egg, she chooses to rank her former lovers' bedroom action and it's hilarious to watch her defend her decision by addressing the camera as if she’s talking to them. We bet she wishes she had just stayed in bed.

This international special sees the Americans and Brits go head to head, but Charlie Puth's delicate stomach and gag reflex doesn't bode well for the home team. We almost feel sorry for him when Rachel Bloom brings her whole team down after she gets outed for lying, but the will he won't he throw up thread throughout the game is just too funny. James Corden seems to take a lot of joy in watching his opponent suffer, and while it might seem cruel, we can't help but laugh along with him.

Chelsea is an open book, so it hardly takes disgusting food to force her to open up. She is absolutely hilarious whether she's sharing stories about getting away with shoplifting, trash talking Justin Bieber, or even just helping James get through the pig's foot he is forced to eat. The best moment is when she's asked to share some intimate details about 50 Cent. Not even slightly phased by the question, she starts looking for visual aids to give James and the audience an extremely descriptive answer.

There's a lot at risk when sitting down at the world's worst dinner table. So it comes as no surprise that Drew Barrymore is so quick to sell Jake Gyllenhaal down the river to avoid eating turkey testicles; though she later tried mend ties with her co-star by taking an 'I heart Jake Gyllenhaal' sign to her show's premiere. As if that isn't juicy enough, James Corden confesses that he stole from Mariah Carey to avoid choking down a thousand-year-old egg. Something tells us he won't be invited to Ms. Carey's home again.

Being a vegetarian doesn’t make this game easier for Christina Applegate, and we can be sure that her pregnant co-star's wildest cravings couldn't match this inedible selection either. Mila avoids drinking clam juice after a very awkward conversation over her husband's 'beer can' or ‘carrot stick,' which she hilariously misunderstands. She's less lucky when she fails to explain the plot of “Jupiter Ascending” and has to chow down some cow's tongue. Somehow, she still calls it 'the best game ever' as Christina looks on in horror.

With over 25 million views, Kendall beat out her half-sisters as the most watched Spill Your Guts or Fill Your Guts video on YouTube. Kendall ranks her nieces and nephews' names to avoid drinking a sardine smoothie, but when she's asked a question about her sister Kylie, the camera cuts to her mother telling her to drink the clam juice rather than answer. To make this moment even funnier, earlier in the game the cameras show James' mom giving him an out just so that she doesn't have to watch her son eat cod sperm.

Isla Fisher and Niall Horan make a great team as they face off with James and Ewan McGregor. Isla opts for a gulp of salmon smoothie rather than allow her teammate to cause a media frenzy by answering a question about his ex-bandmates, and chaos ensues when she gets the smoothie in her hair while determined to spit it out. In turn, when Isla is asked a personal question about her husband, Niall helps her out by doing his best Borat impression, cracking up Isla, and all of us too.

What do you get when you put a top chef in front of a table of ingredients? Gordon Ramsay ups the ante by creating new dishes from the stomach-churning food choices, and while we can’t help feeling smug that we're only watching, we also can’t stop laughing as their concoctions get more and more out of control. James compares the dishes to eating at one of Ramsay's restaurants, essentially biting the hand that's feeding him, and things peak when Ramsay has to eat a chicken's foot in salmon ice cream, topped with clam juice.

While most people might look at the table with disgust, Jimmy Kimmel decides to dive right in before the game actually begins. He seems perfectly happy with the delicacies and even tries to share some bull's penis with an audience member. Jimmy confronts James about his Carpool Karaoke experience with Britney Spears, making James break into a sweat, and us break out in laughter. James barely has time to recover when he can't name two camera men and has to wash down his embarrassment with a fish smoothie.

We all waited with bated breath when Kim had to address the pregnancy rumors surrounding her sisters. While she didn’t have any problem ranking her family's fashion sense or outing her husband's most embarrassing quality, Kim kept schtum about the rumors and drank the sardine smoothie instead. When James had to pick his least favorite Kardashian, even Kim couldn't help cracking up, but she got him back when she asked him to pick his favorite sister, forcing him to take a bite of cow tongue. The things we do for family...
