Al Roker opened up an embarrassing incident during his visit to the White House in 2002. The weatherman confessed in an interview with NBC's Dr. Nancy Snyderman on "Dateline NBC" that he had an accidental "dumping" episode which was believed to be a common side effect from the gastric bypass surgery he just had back then.

"When you have a bypass and your bowel has been reconstructed, you think you're pretty safe," he said. "I probably went off and ate something I wasn't supposed to. And as I'm walking to the press room, [I'm thinking] well, I gotta pass a little gas here. I'm walking by myself. Who's gonna know? Only a little something extra came out. I pooped my pants."

"You pooped in your pants," Snyderman asked to confirm, to which he answered affirmatively, "I pooped my pants. Not horribly, but enough that I knew." The doctor explained, "Which is a common side effect of this surgery." He explained what happened later, "I was panicking, so I got to the restroom off the press room, threw out the underwear and just went commando."

In the interview promoting his book "Never Going Back", he revealed that he used to overindulge in fattening food, "It was one of those things where, to a certain extent, you don't feel worthy ... you're going to be found out as a fraud, you're not as good as you think you are, all those different things combined. And, I like food. But beyond having a good piece of steak or something like that, I'd have to have two steaks."

After failing at numerous diets, Roker had the gastric surgery in 2002 to make good on his promise to lose weight to his ailing father. He lost more than 100 pounds since going under the knife. When asked about his sex life post the surgery, his journalist wife Deborah Roberts, who accompanied him in the interview, assured him, "Honey you're always good."

His struggle to lose weight is also explained in the book. "It brings you up short, but even that wasn't really enough to say 'you've got to do something about this,' and that's the problem. People think that the folks in their life who are overweight, 'I'm going to just help them.' It's not a help. We know we're fat," the "Today" anchor said.
