Veteran television host Al Roker admitted this week that he pooped his pants while covering an event at the Bush White House, all thanks to a recent bowel reconstruction surgery.

"I probably went off and ate something I wasn't supposed to," he told "Dateline NBC" on Monday, relating a story he tells in his new book, "Never Goin' Back: Winning the Weight-Loss Battle For Good." "And as I'm walking to the press room, 'Well, I gotta pass a little gas here.' Well I'm walking by myself, who's gonna know? And something a little extra came out."

Roker said he panicked and ran to the restroom, then threw his underwear away and "went commando" for the rest of the assignment.

Appearing on NBC's "Today" on Tuesday morning, Roker seemed to lament admitting to the embarrassing story, saying he just wanted to let people know the risks of gastric bypass surgery, which he says helped him lose 160 pounds.
