Dr. John Oliver Burns. Oz in the mental health segment on “Last Week Tonight”

John Olivier mocked the Pennsylvania GOP Senate candidate Mehmet Oz with surgical precision on Sunday’s “Last Week Tonight.” (Watch the video below.)

In a segment where Mental Healththe host teased a retro black-and-white clip of nurses applying cosmetics to female patients to “tip the balance between hopelessness and healing.”

Oliver was appalled. “I don’t know what’s more alarming about this, nurses being forced to take on the skills of a Sephora brand ambassador or the fact that ‘can makeup cure sadness?’ looks like an episode that Dr. Oz certainly did.
