Per eyewitness accounts, Jeong appeared to initially think the woman was a heckler, but then rushed to help after other audience members made it clear the woman was suffering a medical emergency. It was such flawless timing: "Ken just jumped from the stage to help", audience member Heather Holmberg said in an interview with USA Today.
More serious fans will know that the 48-year-old Jeong also happens to be a trained physician.
Not to leave the crowd disappointed, Dr. Ken (which is also a semi-autobiographical series he stars in on ABC) returned onstage to finish his set.
"He couldn't see what was going on with the lights". He was playing with them from the stage for a second and it was like, 'No, no, no. He was assisted by a member of the audience who is an emergency medical technical, Holmberg tweeted.
