Ryan Reynolds has enlisted yet another star to raise colon cancer testing awareness. Dallas Cowboys quarterback Dak Prescott stars in the latest ad for Lead From Behind and talks about colon cancer screening. It starts by him getting railed by non-fans. Dak gets lucky, though and only has to focus on the at home screening test and doesn’t have to get a colonoscopy on camera like Reynolds did. There’s even a bonus with the kit: you get to put a sticker of something you’d like to poop all over on the bottom of the collection container. Really. You can see the hilarious ad, which is NSFW, below.
