When you're a super/ultra/mega pop star, you have to strike while the iron's hot. So it's no surprise that musicians lend their music to an array of products.
But even I was a bit perplexed why Ke$ha decided to allow her song "Tik Tok" to be attached to a dancing sock monkey wearing a scarf. Worse yet - my half-sister got this thing as a gift.
I guess I'm just grateful that this didn't come with a rainbow gun.
