In a new video brought to us by the Merc With a Mouth himself, Ryan Reynolds, Deadpool teaches males how to self-exam themselves for testicular cancer. No, this is not a joke and yes that was an actual sentence.

So, in case you have no idea how to check your “smooth criminals,” don’t know what an epididymis is, or like puns, we highly recommend you watch this video. Who knows, you might even learn a thing or two and isn’t knowledge the greatest gift of them all?

See the full video below and then immediately wish you had Deadpool as your sexual education teacher. Are you going to see Deadpool in theaters? Let us know in the comments below! Deadpool, directed by Tim Miller and starring Ryan Reynolds, hits theaters February 12th.

Something to touch yourself to. #deadpool.https://t.co/AyJJNsQcjg
