'True Blood' Star Alexander Skarsgard Takes Naked Instagram Pic...On the Toilet. In Antarctica.

If you're a fan of "True Blood," you're probably pretty used to seeing Alexander Skarsgard naked.

But probably not like this.

Skarsgard showed up on some Instagram feeds today in this pic from friend Inge Solheim. In the pic, the Swedish actor poses completely naked on a toilet in the middle of Antarctica.

Why? We have no idea.

"#southpole -30C What are you reading Alex? The script for season 7 of #truebloodHBO?" wrote Solheim with the pic. We're less concerned with what he's reading and more concerned with why that toilet doesn't have any walls around it. Or a space heater or something.

Of course, Skarsgard is no stranger to nudity; after all, he's taken it all off for the camera many times on "True Blood."

In fact, during the season six finale of the show, Skarsgard went full frontal, exposing his penis. According to co-star Stephen Moyer (who plays Bill), that wasn't even the original plan; Skarsgard just doesn't like wearing his privacy sock on set.

We admire your confidence, Alex. And your Nordic resistance to cold. Because with all this Polar Vortex stuff going on, that looks mighty uncomfortable.
