Bill Maher has slammed Rush Limbaugh and other leading Republicans over their reaction to the Louisiana oil spill on his program 'Real Time. '

He slams Limbaugh for saying the oil spill was "natural."

Quoting the right wing host, Maher stated "Limbaugh said 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.

Maher also went after Texas governor Rick Perry who says it was an act of God. "I think it was an act of Dick Cheney," Maher said, "And it shows the disastrous results of having lobbyists write laws.

Newsweek columnist George Will was another target:

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

Maher also compared Bush and Obama over Afghanistan and the war on terror

"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?
