Matt Damon doesn't need to watch Gone Girl to catch a glimpse of Ben Affleck's penis because — are you sitting? — he's seen it "many times" before and probably has a better mental snapshot than its "full-frontal film debut" provided.

The 44-year-old actor confirmed his familiarity with Ben Affleck's package with a TMZ photographer last night, who asked if he had seen his friend's dick shot in the critically acclaimed film.

We just assumed these bro-friends had seen each other in the buff before, seeing as they were roommates in Boston in their pre-fame days. But something about Matt's nonchalant attitude about his buddy's junk has us longing for more details.

The ball is in your court, Ben.
