Watch: Allison Williams from Girls sing

We have no idea what this is in aid of or indeed, why it even exists but Lena Dunham pointed it out on her twitter and where Dunham points, we follow. It's Allison Williams, better known as Marnie from Girls, performing another slow cover of a song. Remember that time on Girls when she performed Kanye West's Stronger to an embarrassed audience of techie hipsters? It was horrific, right?

This time, it's Ke$ha's Tik Tok. She has a sweet voice and it's already garnered 6 million views. A note from the pianist says it's supposed to be ironic but sometimes some things are so painful and so, what's the word? - bland that they transcend irony and become simply something that someone did one time. Judge for yourself.
