Remember Rickrolling, that devious Internet meme whereby someone pretends to link to something relevant to the topic at hand, but then when you click on the link, it's freaking Rick Astley singing "Never Gonna Give You Up"? (If you haven't heard of Rickrolling, where on earth have you been? Ahhh. Living your life offline. Carry on then!) Anyway, someone did a fine editing job by Barackrolling McCain at his own convention. Hilarious!
