Uh, Wut?

Why is it that when I go to see the lyrics for the song Bliss by Muse, there's an informative ad on the page from Gillette on how to "make the tree taller by shaving the bush?" Is it because the name is Bliss? Am I missing something? (Oh, there's an ad for Ecstasy, a product from Trojan, there as well.)

And do people really do that? (That's a rhetorical question, kids, in case you're wondering.)
