In Dr. Seuss' classic tale And to Think That I Saw It on Mulberry Street, the narrator strives to create an ever-more bizarre tall tale to satisfy a demanding audience. Rush Limbaugh and Sean Hannity seem to be taking their cues from Dr. Seuss' young Marco with their increasingly large -- and false -- claims about the Obama administration's response to the Gulf oil spill.

Rush got the ball rolling last week, when he claimed that President Obama "waited eight days" to deal with the spill. At the time, Media Matters pointed out that this was false; the administration immediately dispatched officials and the Coast Guard to the area to work on the response.

Hannity, perhaps trying to one-up his fellow right-wing host, went on the air that night and claimed that the administration "sat back for 9 days and they did absolutely nothing."

But that apparently wasn't enough for Hannity, because tonight, he increased that number, asserting that "for 10 days the government did nothing" about the spill.

Poor Sean. Sure, he'd beaten his own record, but earlier that day, Limbaugh had set the bar even higher. Here's Rush:

That's right. “They didn't respond -- this administration -- for 12 days after the BP rig blew up.”

Your move, Hannity.
