Shocking! But false.
UPDATE: A 274 post DUmmie weighs in with "Concerned - People need to know: "Bush's fishing" photo a fake":
I'm no friend of the Bush's, but I'm a stickler for truth and accurracy.
I've been seeing the infamous photo of Bush Sr/Jr holding up a just-caught fish in the flooded streets of N.O.
...just about everywhere (even receiving it via e-mail) without any clarification/attribution that the photo is a Photoshopped fake.
Funny, but fake. I think a lot of people using it think it's real.
I'm a stickler for accurracy two, but I'm sure most people, or at least most non-DUmmies, are aware it's a fake.
