Al Roker -- Pisses on his Own Show

First he sharts ... and now Al Roker is urinating all over the "Today" show -- figuratively speaking (actually, the sharting was real).

Roker groused to a reporter that our story on Al pooping his pants at the White House should not have blown up the way it did because it was old news.

But as Al explained ...he spoke about the sharting incident on the "Today" show several days before and nobody cared -- it was only when the story appeared online that anyone noticed.

In so many words ... he's saying the "Today" show is irrelevant.
