Video: Al Roker confesses 'I pooped in my pants in White House'

When NBC's weatherman Al Roker appeared on Dateline Sunday, he made an embarrassing confession to Dr. Nancy Snyderman. After gastric bypass surgery in 2002, he pooped in his pants at the White House and had to execute smart moves to conceal the evidence.

TheToday Show meteorologist and Weather Channel host appeared on Dateline to promote his new memoir "Never Goin' Back: My Weight Loss Journey." He talked about his March 2002 gastric bypass surgery and opened up, presumably for the first time, about a little incident that happened while attending an event in the White House, when George W. Bush was the president. He takes us through the details of his experience with disarming honesty. Warning: Graphic content: The story begins with a furtive ninja plan to release a little fart in an empty corridor. But things go wrong when the release force also liberates enough — well, you know — to soil the weatherman's briefs. Roker: "When you have a bypass and your bowels [have] been reconstructed, you think you're pretty safe. 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." Panic. Plan B: Make a dash for the nearest bathroom, dump the offending briefs in a trashcan and "go commando" for the rest of the day. Nancy Snyderman: "You pooped in your pants." Al Roker: "I pooped my pants. Not horribly, but enough that I knew.” Doctors have a name for the "pooping problem" associated with gastric bypass surgery.They call it: "dumping syndrome." (not the briefs in the trashcan, but the....) According to Mayo Clinic, dumping syndrome, "also called rapid gastric emptying, dumping syndrome occurs when the undigested contents of your stomach move too rapidly into your small bowel. Common symptoms include abdominal cramps, nausea and diarrhea." Confessions of a Weatherman: You may also want to hear Roker talk about his sex life in the video.
