Homo for the Holidays

S2 E7: When Will (Eric McCormack) and Grace (Debra Messing) meet Jack's (Sean Hayes) mother (guest star Veronica Cartwright) and learn that not only is she unaware that her son is gay, she believes he has had a romantic relationship with Grace, they invite her to Thanksgiving dinner with Jack hoping to force the issue into the open. But nobody is prepared for the holiday surprise that she has for them. Megan Mullally also stars.
