Alexander Skarsgard is one of the sexiest men in Hollywood, and he also happens to be one of the nudest. But throughout his proud nude history, did you know that he only stripped down for one single penis scene? 'Tis true! It all goes down at the end of True Blood season six, when (SPOILER ALERT) day-walking vampires discover that their ability to not fry under the sun has vanished. We see Skarsgard as he's enjoying the sun in his native Sweden on a snowy mountaintop, when all of a sudden he bursts into flames, causing him to get up out of his lounge chair. This gave the world its only look at Skarsgard's perfect penis! You could say that this scene is fire. Enjoy...
