Turns out that convincing Channing Tatum to wear a ball gag and dog leash for his crazy cameo in 2013’s This Is the End really wasn’t that hard for Seth Rogen.

The actor recently revealed the backstory behind Tatum’s bizarre role on SiriusXM’s Andy Cohen Live, and even read Cohen the hilarious emails he exchanged with the Magic Mike star about the part.

The initial email, sent back in 2012, begins innocently enough. “How’s it going dude? I have what is probably the single oddest offer you will ever get, so here it goes … ”

He then lays out the general premise of the movie, which was at that time was called The End of the World. “It’s a somewhat crazy movie in which me and other actors play themselves stuck in James Franco‘s house as the apocalypse happens,” Rogen explains, adding that, “We have a very special role that we’d like you to play.”

Rogen then reveals (in great and NSFW detail) that the part he has in mind is the deranged sex slave of apocalyptic gang-leader Danny McBride.

“The Gimp is wearing a wrestling mask, and when he pulls it up we would love nothing more than for it to be you underneath. I know this is crazy, but we really think it will get a massive laugh,” he reads.

He added, “Please don’t take this the wrong way or be insulted by this, we just think it’s a great joke and you would be great doing it.”

Tatum responded to the email just three hours later with three points: “One, what the f—? Two, that’s the craziest s— I’ve ever heard. Three, when and where do I show up?”

He then joked, “All I’ve wanted ever is to be Danny’s slut, is that weird? Don’t tell him I’d be embarrassed.”

Asked how Tatum felt about wearing the character’s skimpy, bondage-themed outfit, Rogen told Cohen the costume embellishments were all Tatum’s idea.

“He pushed it so much further than I ever could have imagined.”
