Michael Angarano

Will (Eric McCormack) returns from vacation to discover that Grace's (Debra Messing) romantic relationship with neighbor Nathan (Emmy-winning guest star Woody Harrelson, "Cheers") is humming along - but Nathan feels neglected when Will and Grace resume their chummy friendship, complete with their own private language and code. Meanwhile, Jack (Sean Hayes) proudly takes his newfound son (Michael Angarano) shopping for school at Barney's while Rosario (Shelley Morrison) and Karen (Megan Mullally) each cruise the merchandise looking for the perfect "anniversary gift."

When Grace (Debra Messing) is invited to her ex-fiancé’s (guest star Tom Verica) wedding, she hauls along a reluctant Will (Eric McCormack) just to convey a false air of success - but when she denigrates the bridegroom's faults at the rehearsal dinner, she's confronted by a weeping bride-to-be (guest star Jennifer Aspen) who now wants to flee. Meanwhile, Elliot's (Michael Angarano) fuming mother (guest star Rosie O'Donnell) gets in Jack's (Sean Hayes) face when he allows Elliot to frost his hair and demands that he never see his son again. In addition, Will poses as a swinging tennis pro until he meets his match. Megan Mullally also stars.

Jack (Sean Hayes) is puffed up with paternal pride as he escorts his long-lost teenaged son Elliot (guest star Michael Angarino) to a junior high school dance but not before he coerces Grace (Debra Messing) into posing as Elliot's date - which only revives her own tortured memories of rejection from school dances many years before. Elsewhere, Karen (Megan Mullally) has great fun at her lawyer Will's (Eric McCormack) expense when she continues to capriciously summon him for bogus "emergencies" - that is, until she really needs him.

Rather than be apart on Thanksgiving Day, Will (Eric McCormack) and Grace (Debra Messing) join Jack (Sean Hayes) and Karen (Megan Mullally) for a festive holiday motor tour of their respective dysfunctional families, including Grace's domineering mother (guest star Debbie Reynolds) as well as Will's willful mom (guest star Blythe Danner, "Meet the Parents") and Jack's step-dad (guest star Beau Bridges) - with unsettling results. Meanwhile, back home, a waiting Rosario (Shelley Morrison) bastes and tastes their juicy turkey. Helen Slater ("City Slickers"), Jon Tenney ("Brooklyn South"), Lainie Kazan ("The Nanny") and Kenneth Mars ("The Producers") also guest star as other bizarre family members. Part 1 of 2.

Will (Eric McCormack) and Grace (Debra Messing) elect to disagree when it comes to choosing sides during a mayoral election; she supports the Jewish candidate and he's voting for the gay nominee. Sean Hayes and Megan Mullally also star.
