You can count on Al Roker to tell it like it is.

And he did just that - sharing a little too much information - in a Datelineinterview on NBC with Nancy Snyderman, and his soundbite is quickly becoming legendary.

Roker,58, who has written a new book about his struggles with weight loss,sat down with Snyderman to talk about gastric bypass surgery.

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."
