Fagel Attraction

S4 E23: After his laptop computer is stolen, Will (Eric McCormack) meets a sociable police detective (Oscar-winning guest star Michael Douglas, "Wall Street," "Traffic") who takes a special interest in his case as they go undercover - but Will doesn't know that the gumshoe is secretly participating in Jack's (Sean Hayes) therapy group for gays. Elsewhere, Grace (Debra Messing) is again hassled by her psycho neighbor Val (guest star Molly Shannon, NBC's "Saturday Night Live") who "opens" a rival design business and prospers by stealing Grace's ideas. Barry Livingston ("My Three Sons") guest stars as Grace and Val's potential client. Megan Mullally also stars.
