Do I have to explain what's wrong with this?

Seriously. I mean, apart from the disgusting appropriation of what was once an arguably decent song (and the completely non-sequitur G'n'R insert—wtf mate?), this is a performance on the Today show. At like, ten in the morning. Look at all those kids in the audience—and then you've got Fergie, groping herself onstage, practically humping the guitarist's leg, and crawling around panting. I—it—just, why?
