Hugh Hefner can't tell them apart. Will Playboy readers be able to?

Indeed, Karissa and Kristina Shannon are featured in the latest issue of the men's magazine. No shock there.

Somehow, though, the twins are clothed in the two photos that have been released.

Don't worry, fellas: we know where you can see Karissa and Kristina Shannon nude!

In the new issue, Karissa and Kristina sport matching sailor hats and jean shorts, continuing their tradition of dressing alike and doing everything together.

Including Hef, of course.

“We feel as if we’re one. In each other we always have a best friend,” the twins said, failing to mention that in one another, they also have an old, wrinkled penis.
