For some reason, Al Roker admitted his most embarrassing moment, with a straight face, last night on "Dateline": "I pooped my pants."

The messy incident occurred while Roker was covering a White House event just a month after his March 2002 gastric bypass operation.

"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 your pants," confirmed the interviewer, deadpan.

"I threw out the underwear and went commando," continued Roker.
