You've Been Barack-rolled
(Tip o' the tinfoil hat to Jill @ B@B.)
While John McCain dismisses his attack ads on Barack Obama as mere fun, some enterprising Youtuber redefines fun by making this video that's also a redefinition of "Rickrolling", an irritating practical joke that directs people to a certain vile 80's video by a one-hit wonder who shall remain semi-nameless.
But this is a cool and funny video that makes ingenious use of Obama's speeches and press conferences.
