Al Roker may be good at predicting weather, but there are some things even he can't predict.

The TODAY weatherman — who underwent gastric bypass surgery in March 2002 — appeared on Dateline on January 7, 2013, and revealed that his most embarrassing moment came a month after his surgery, while he was covering an event at the White House.

"I probably went off and ate something I wasn't supposed to," Al tells the news show. "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," Al confesses. "I pooped my pants." Yikes!

Al says he then ran to the restroom and tossed his underwear in the trash, meaning he went commando for the rest of the day. Let's just say that, after telling this story, we wouldn't be surprised if Obama doesn't invite Al back to visit anytime soon.

You can add this to the list of things that we never needed to know about. Thanks so much for sharing, Al!
