Former Late Late Show host James Corden left his CBS talk show a year ago and moved back to the UK.

There, he said Tuesday to Jimmy Kimmel, he’s frequently trying to convince other that he wasn’t fired from the show instead of leaving of his own volition.

“People are very nice. But no one believes that I wasn’t fired,” said Corden, who was promoting his new podcast, This Life of Mine. “People will honestly be like, ‘You don’t have to give me that bullshit. It’s fine, mate. If you got fired, you got fired.’ Because nobody thinks you would ever leave what is—let’s be honest—a cushy existence.”

“Can’t you get a letter from CBS saying that you were not fired, that you left of your own free will?” Kimmel asked.

“I would, except they don’t know what CBS is,” Corden joked.
