W. and Karl Rove "shared an array of fart jokes," Mr. Woodward writes. A White House aide put a toy that made a flatulence sound under Karl's chair for a morning meeting on July 7, 2005. When officials learned of the terrorist attacks in London that day, the prank was postponed. But several weeks later, "the device was placed under Rove's chair and activated during the senior staff meeting. Everyone laughed."
When a senior administration official said the White House was run by "kids on Big Wheels, who talk politics and know nothing," maybe he wasn't speaking metaphorically!
Correction 9:14 AM: Posting before my coffee kicks in is always a mistake. Per SomeCallMeTim's comment below, it was "a senior White House official" who gave the "Big Wheels" quote to Ron Suskind, not (necessarily) John DiIulio as this post previously stated.
