Step Brothers Super Fan Got Will Ferrell & John C. Reilly's Faces Tattooed On His Butt! Watch John's Horrified Reaction!

John C. Reilly thinks some Step Brothers fans need to take it down a notch.
On Thursday’s Conan, the Kong: Skull Island actor he appreciates the love people still have for his 2008 comedy with Will Ferrell — but thinks one fan went a little too far with a super cheeky tattoo!
The 51-year-old then showed us what he was talking about — a photo of a bare-assed man with tattoos of Reilly and Ferrell’s faces on his buttcheeks!

While his Step Brothers character Dale would be all about the insane booty ink, the actor admitted he wasn’t a fan, quipping:

“The only thing that comes between me and Will these days is the usual sh*t.”

LOLz! Either way, that’s some serious fan dedication!
