The YouTube clip quickly notched up 2.2million views, prompting Sanity to broadcast a response in a segment he called "Hollywood Vs Hammas".
"Russell, if you’re watching, which I know you are, take a close look at the TV so I can educate you because you’re kind of dumb and ignorant," he said during the panel discussion, during which Brand was ridiculed by a guest as looking "skanky" and as if he "cooks meth and sleeps in his car".
So Brand issued a second video response, "Israel/Palestine, Russell Brand/Sean Hannity: Round 2", in which he picked apart Hannity’s show piece by piece.
"Apparently Russell can’t get it through his thick head and possibly fathom that this is the reality," Hannity had said to camera.
Cut to Russell: "It’s not a reality. It’s a combination of speculation, conjecture, and highly contextualised and selective information. That’s not reality. It’s piecing together a narrative that fits in with Fox’s world view and his own bigoted world view," he said.
"That’s not reality, it’s a tiny aperture through which bigoted and particular information is glimpsed. That’s sort of the opposite of all encompassing, wonderful, unknowable reality."
Brand also said the term "terrorist" is provocative rhetoric once used to describe "cuddly" Nelson Mandela and anyone else who dared challenge the status quo.
