The Young and the Tactless

S3 E21: Grace's (Debra Messing) new neighbor (Emmy-winning and Oscar-nominated guest star Woody Harrelson, "Cheers," "The People vs. Larry Flynt") is a slovenly lout whose disheveled lifestyle and grungy habits put him at odds with her well-ordered world - and her only hope to dislodge Pigpen is to provide him with enough romantic advice to reunite him with his long-suffering girlfriend. Meanwhile, a scheming Karen (Megan Mullally) dumps her visiting and elderly mother-in-law (guest star Ellen Albertini Dow, "The Wedding Singer") on Will (Eric McCormack) and Jack (Sean Hayes) just when they score tickets to an exclusive club for that night only.
