Emmy-winning Practice star Camryn Manheim will guest star on NBC's Will & Grace this season as a loopy psychic whom Will (Eric McCormack) seeks out for advice. The episode, "Gypsies, Tramps and Weed," is scheduled to air in November. In the story, Will reluctantly uses a birthday gift certificate from Grace (Debra Messing) to consult a psychic about his future and encounters Sue (Manheim), an absent-minded psychic who operates out of her disheveled living room and whose predictions leave him reeling.
