Cover art for Skinny Genes lyrics by Eliza Doolittle

No idea why, but I totally love that the title is "Skinny Genes" eventough she's actually singing about Skinny Jeans :D It doesn't make sense to me, yet I love it!

It's titled "Skinny Genes" because he's the bottom of the gene-pool, in that he sucks in life at pretty much everything (except sex, clearly).
