Afterundergoing the surgery in 2002 and losing more than 100 pounds, Rokerrecounted that he was visiting the White House about a month after thesurgery.

"When you have a bypass and your bowel has beenreconstructed, you think you're pretty safe," he explained. "I probablywent off and ate something I wasn't supposed to."

As he waswalking to the press room, Roker felt like he had to "pass a little gashere. Only a little something extra came out," he said.

"You pooped in your pants," said Snyderman.

"I pooped my pants," confirmed Roker. "Not horribly, but enough that I knew."

"Which is a common side effect of this surgery," Snyderman said.

"Exactly,"he said. "So, I was panicking. So I got to the restroom of the pressroom, threw out the underwear and just went commando."
