"I actually once misjudged a fart on stage, which ended up being a shart," he told Australian radio station Nova FM. "It was midway through a performance and I was kind of like, really lively, and then halfway through I was like, 'All right, I'm just going to stand for the rest of the performance, and hope it's over soon, and then go home and throw these trousers out.'"
Ed also said he passes gas while performing "all the time," and admitted to having gone three days without changing his underwear.
