Because there's literally nothing I can say about this (other than it's insanely interesting that it exists), I'll go with Stephen Malkmus & The Jicks performing on Fallon last night. The group performed "Senator," the lead-single from their recently released Mirror Traffic (out now via Matador Records).
Notice one subtlety in the lyrical change. Hint, it's the blow job part.
