As Twitchy told you, Roseanne Barr found herself in some very hot water after a pretty disgusting “joke” about Valerie Jarrett being the love child of the Muslim Brotherhood and the Planet of the Apes.

For comedienne Wanda Sykes, a consulting producer on “Roseanne,” Barr’s tweet was the straw that broke the camel’s back:

Never mind that Roseanne was awful and insane before she made her stupid Jarrett “joke.” Why is this what it took for Sykes to walk away?

It’s worth noting that this isn’t the first time Roseanne has taken what could be construed as a racist (and definitely misogynistic) swipe at a black woman:

And let’s not forget about this:

But Sykes still signed on to work on “Roseanne” after all that. Why?

Wanda’s not exactly an angel when it comes to “jokes,” either. Her 2009 performance at the White House Correspondents’ Dinner managed to raise the eyebrows of even some liberals:

Sykes was at her most vicious on the subject of Rush Limbaugh. “Rush Limbaugh said he hopes this administration fails. That’s like saying, ‘I hope America fails.’ Or that ‘I dont care if people are losing their homes, their jobs, our soldiers in Iraq.’ He just wants the country to fail. To me, that’s treason. He’s not saying anything differently than what Osama Bin Laden is saying.” Then, turning to the president, Sykes added, “You might want to look into this, sir. Because I think maybe he was the 20th hijacker. But he was just so strung out on Oxycontin that he missed his flight.”

Realizing she shocked the crowd with that remark, she said, “Too much? But you’re laughing on the inside…”

But she wasn’t done. “Rush Limbaugh [says] ‘I hope the country fails.” I hope his kidneys fail. How about that? He needs some waterboarding, that’s what he needs.”

But Roseanne went too far?

Roseanne’s “joke” was indeed offensive. But given Sykes likening Rush Limbaugh to a terrorist and joking about his death, her moral high ground is pretty shaky, too.
