When someone needs medical attention in a public venue, you might yell out, “Is there a doctor in the house?” But that is not necessary when you go to see a comedy show headlined by Ken Jeong, because you already know that there is a doctor right up there on the stage.

Yes, before Jeong’s acting career took off, he was a legitimate practicing physician. And he had to put that medical training into action this past Saturday in the middle of his set at the Stand Up Live Comedy Club in Phoenix, Arizona.

When a commotion came over the crowd, Jeong initially thought he was being heckled, but when it was made clear to him that a woman was having a seizure, he jumped off the stage and rushed to her aid, staying by her side until the paramedics arrived. After she was taken to a hospital, he got back onstage, received a round of applause, and then completed his set.

Even without his medical career, Jeong could be considered a bit of a Renaissance man, as his long list of IMDb credits over a 20-year acting career can attest to. He has memorably played medical professionals in Knocked UpBob’s Burgers, and his short-lived sort-of-autobiographical sitcom Dr. Ken. But if you’re looking for his greatest acting triumph, it would have to be his six-season stint as the ridiculous, but oddly affecting Spanish professor Ben Chang on Community.
