This week's Mainstream Media Scream features HBO's Bill Maher calling former President George W. Bush's bike ride with wounded warriors "nauseating."

On his Friday night show, Maher said, "George Bush, over the Memorial Day weekend, held the Wounded Warrior 100K, which was a kind of a celebration for wounded warriors who came back from Iraq and I guess they walked or ran or something on their prosthetic limbs. And I found this to be nauseating. I mean, first he sends them off to war to get their limbs blown off and then he has them over for a barbecue. This is like the Cleveland guy having a pizza party for those girls he had in his basement."

Media Research Center Vice President of Research Brent Baker explains our pick: "It seems Bill Maher never got over his Bush Derangement Syndrome, but this was a particularly virulent and nauseating stream of it. A reminder of the anger and hatred too many on the left have towards those with whom they disagree."

Rating: Five out of five screams.
