Katie Couric has a starring role in a new public service announcement encouraging colon cancer screenings - and it opens with a clever nod to Sydney Sweeney's controversial American Eagle ad. The video begins with a sultry close-up of Couric, 68, lounging in a denim jacket with a seductive soundtrack. As the camera pulls back, the scene takes a surprising turn. The famed TV personality is seen lying on a gurney, clad in a hospital gown from the waist down, as a medical team prepares her for a colonoscopy.
