Before he was one of the comedic stars of Community and the Hangover trilogy and created his sitcom Dr. Ken, actor Ken Jeong was a practicing physician. And, despite his full-time show biz career, he's still licensed in California.
Given that it's been a while since he's had the chance to see a patient in person—and the fact that Twitter is where people try to crowdsource most of their health information these days—it only made sense for Jeong to drop some serious medical knowledge in this video for Wired. His bedside manner may be a little... brusque, but hey, at least he never sugar-coats his professional opinion.
I know what you're thinking, but no—he's not in your insurance network.
