Jessica Lange and Sarah Paulson got an eyeful when one of their male co-stars showed off his cojones… on accident!

When we asked Viggle LIVE! users to identify the actor in question, respondents were nearly stumped — a very narrow majority answered correctly!

The actor in question was Evan Peters, who flashed his "family jewels," if you will while filming a scene in which his character is whipped by Jessica's nun character in American Horror Story: Asylum, while Sarah's journalist character bore witness.

38 percent of users thought it was Evan, 32 percent thought the flasher was Dylan McDermott, and 30% guessed Zachary Quinto.

"That was literally the first day of shooting." Evan told Vulture in 2012. "I had to wear a cock sock, right? And since I was wearing a hospital gown, I thought, Well, my front's not going to be showing. It's not a big deal. And when they bent me over [laughs], they could see my balls hanging down from the other side."

But Sarah and Jessica were unfazed.

"They didn't even say anything," he recounted. "Sarah just walked over after that take and kissed me on the cheek. I was like, Why? What’s happening? That's when I realized. I was mortified."
