Lily: Santa's still a lie, and I'm not lying to our kids.
Marshall: Baby, it's Santa. Don't you want our kids goin' to sleep on Christmas Eve with their hearts full of hope, their heads full of crazy cough syrup nightmares, knowing that downstairs Kris Kringle is stuffing their stockings full of joy and stuffing his belly full of milk and lutefisk that they left him?
Lily: Milk and lutefisk? Santa doesn't get cookies in Minnesota?
Marshall: Yeah, that's just what Santa needs at 3:00 a.m. when he's battling a snowstorm over the Rockies, a sugar crash. No, Santa needs protein.
