I think most people seen the video of Mike Patton at Lollapalooza, asking, "Are you hearing this shit?", when he heared Wolfmother playing "Woman" in the background of his interview.

I for one thought it was quite funny.  I don't hate Wolfmother but I tend to think they are imitaters.   But it seems Mike Patton has done an about face on his opinion on Wolfmother.  This morning I was watching the repeat of Mike Patton and Imani Coppola guest programming on Rage where they introduced Wolfmother's "Woman" video like so:

Mike: "Hello everybody.  We've got more videos.  The next one is by, probably, my favorite band in the world."
Imani: "I heard about this."
Mike: "Yeah."
Imani: "Yeah, big fans of them."
Mike: "Big fans.  I'm a big fan.  Umm, me and, you know, 8 million other people."
Imani: "Yeah."
Mike: "Umm, genius.  It's basically genius and genius speaks for itself.  Wolfmother."

After the video I was expecting Mike to say, "Nah, just kidding.  They're shit."  But no joy.  Someone has already uploaded this video on YouTube so you can see for yourself.
