All About Christmas Eve

S5 E11: On Christmas Eve, Grace (Debra Messing) is torn when she has only two tickets to "The Nutcracker" musical and can't take both her best friend Will (Eric McCormack) and new husband Leo (guest star Harry Connick Jr.) - but her back-and-forth indecision leaves Will spinning like a Hanukkah dreidel between a dithering Grace and his previous holiday plans with Jack (Sean Hayes) and Karen (Megan Mullally). Mary McDonough ("The Waltons") guest-stars.
