It's a given that nearly every girl is going to fall hard for Brad Pitt or Alexander Skarsgard. And most men are going to find actresses like Mila Kunis terribly appealing. Boooring. The thing that makes fantasy celebrity crush discussions really interesting is when we let loose and reveal that we actually find a celeb who isn't known for his or her sex appeal to be totally hot. We can't explain why -- sometimes it's their sense of humor or the way they carry themselves, walk, laugh, or simply look at us (oh, fine, they're actually looking at a camera, we know). 

Here are 15 celebrities who aren't known for having conventional good looks, but who we can't help but find totally hot.
