OK we’re being a little dramatic, but this playful spot from Ryan Reynolds—we mean Deadpool—has a super important message. Testicular cancer is the most common cancer among men between ages 15 and 35—which just so happens to be the key demographic for this movie. The video is surprisingly informative, instructing men how to do a quick self-check once per month after a shower or bath. And it’s hilarious. How could it not be with the number of euphemisms for testicles Reynolds uses (happy sack, man berries, and smooth criminals, to name a few)? You can get more of the humor (and puns) when Deadpool hits theaters February 12.
