Why is Ke$ha Obsessed with Beards?

Even if I knew the answer to this question, I still just wouldn't understand it. It's no secret that Ke$ha is kind of all over the place most of the time. But, in case you need a little proof...

Ke$ha appeared on Conan last night and said that she made a Tumblr account full of pictures of her with beards in her mouth. Her page is titled "Put Your Beard In My Mouth." I can't make this stuff up...see for yourself:
