There are a lot of things you shouldn’t do while drunk: drive, call exes, tattoo your friends. Justin Theroux, the man made super famous for getting Jennifer Aniston to agree to marry him, did one of those things. Any guesses as to which?

Door No. 3, please. There you’ll find Justin and bud Scott Campbell, whom you may know as the husband of pregnant Lake Bell. During the Free Arts Annual Auction in New York City on April 30, Justin explained what a typical guys’ night looks for Justin and Scott.

“We became friends first, and then we had a couple drunken tattoo nights,” he explains, which we’re all for, seeing as Scott’s a professional tattoo artist who’s responsible for most of Justin’s own body art. Then the future Mr. Aniston adds: “And I’ve tattooed him, too, by the way.”

“I’ve done a bunch of them,” he continues. “I did a really great wolf’s head. I did an amazing skull and crossbones. I did a stunning yin-yang on him.”

Just when you think Justin may have found his true calling he lets slip this little caveat: “I messed every single one of them up. But he kind of likes it.”

Even when he’s sober?
