Just in time for Halloween'Today' anchors Lester Holt, Amy Robach and Jenna Wolfe joined the cast of SyFy's 'Ghost Hunters' to search for spirits at Eastern State Penitentiary in Philadelphia. Mighty brave, given that the abandoned prison is supposedly a hotbed of paranormal activity.

Aside from noises and shadows, Holt's search doesn't reveal much. But both Robach and Wolfe get some serious scares as they trek through the prison's hospital wing in the dark of night.

Grab your trusty infrared camera and EMF meter and watch the two-part series below.
