Meredith Vieira got down and dirty–and was barely recognizable–on The Today Show’s Halloween celebration Friday. In keeping with her former co-hosts’ Peanuts theme, Vieira dressed up as their messy friend Pigpen.

Showing up in a cloud of dust–or gray tulle–Meredith Vieira wore dirty overalls and a scraggly hairstyle befitting the sloppy character.

Her presence came as sort of a surprise to Matt Lauer, Savannah Guthrie, Al Roker, Kathie Lee Gifford, Hoda Kotb, and more.

“I never miss (Halloween),” she said. “They drag me back. This is typecasting.”

Did you see The Today Show on Friday? Al Roker was Charlie Brown, playing opposite Matt Lauer as Lucy. Savannah Guthrie was Charlie Brown’s little sister Sally. Kathie Lee Gifford and Hoda Kotb were Snoopy and Woodstock. Regis Philbin also surprised fans on the plaza when he showed up as the Red Baron.

Of course everyone on The Today Show went through hours in makeup and wardrobe to pull off their Halloween personas. Meredith Vieira, however, appears to have undergone a bit more of a transformation than the rest.

Kudos to all the Today Show stars on another great year of surprising their fans for Halloween.
