On Thursday, Corden went after fellow late-night host and TV neighbor Maher -- who shoots Real Time in the same CBS Television City building as The Late Late Show -- for his monologue last Friday calling for the return of fat-shaming. Corden said Maher sounded like a "d*ck" with his comments. "Fat-shaming doesn’t need to end it needs to make a comeback," Maher said. "Some amount of shame is good. We shamed people out of smoking and into wearing seat belts. We shamed them out of littering and most of them out of racism. Shame is the first step in reform.” As Corden pointed out, fat-shaming doesn't need to make a comeback "because fat-shaming never went anywhere. I mean, ask literally any fat person. We are reminded of it all the time. On airplanes. On Instagram..." Corden added: "Now there's a common and insulting misconception that fat people are stupid and lazy. And we're not, right. We get it. We know. We know that being overweight isn't good for us. And I've struggled my entire life trying to manage my weight, and I suck at it. I've had good days and bad months. I've basically been on off-and-on diets for as long as I can remember and, well, this is how it's going," he said, gesturing to his body. Corden reminded Maher that fat-shaming leads to one thing: a feeling of shame. "And shame leads to depression, anxiety and self-destructive behavior -- self-destructive behavior like overeating." The term fat-shaming, he says, "is just bullying. And bullying only makes the problem worse." Corden ended his nearly eight-minute monologue with a message to Maher: "Bill, please hear me when I say this. While you're encouraging people to think about what goes into their mouths, just think a little harder about what comes out of yours."
