Bill Maher Slams Rush Limbaugh, Dick Cheney, George Will Over BP Oil Spill, Climate Change Denialism (VIDEO)

On "Real Time" this week, Bill Maher took on conservatives for dismissing the Gulf oil spill and the climate change movement.

"Rick Perry says it was an act of God. I think it was an act of Dick Cheney," Maher said, referring to the Bush administration's energy task force. "And it shows the disastrous results of having lobbyists write laws."

Later in the program, he slammed Rush Limbaugh for dismissing the oil spill as "natural."

Here's his quote about the oil spill "The ocean will take care of this. It's as natural [the oil] as the ocean water is." That's right, a petrochemical stew is very natural to wetlands. You know what, you dipshit? Mercury's natural too -- you don't put it in your Cheerios.

Finally, he revisited the debate he had with George Will over oil on "This Week".

"Why haven't we actually gotten off the oil? One reason is global warming deniers like George Will. He knows better."

Maher also discussed the failed car bomb attack in Times Square and criticized the war in Afghanistan:

Let's compare Bush to Obama in a more serious way. Bush always used to say "We're fighting them over there, so we don't have to fight them over here." And we would all go "Oh, you moron." But that's basically the policy Obama is doing. Obama may call it something different, but doubling down in Afghanistan and sending more troops in there is fighting them over there, so we don't have to fight them here. But I'd like to say, "Memo to the administration: They're already here." So what is the point of us being in Afghanistan?
