"The First No L" is the ninth Christmas-themed episode of the FOX animated sitcom Family Guy, that aired in the show's nineteenth season.
Plot
When Lois insists on the family helping her with Christmas, they blow it and she decides to leave them on their own for the holidays to see how they would do. At first they despair, but things actually go their way and they have a good time. However, Lois, who told her family that she was going to take care of cousins in Mexico, holds up at a motel with a pair of binoculars where she can spy on them and wait for them to call begging her for help. Seeing that they've become a successful and loving family without her, she vows revenge.
In a stunt worthy of the Grinch, she sneaks into the house to take all of their Christmas goods, but not before she ends up doing the household chores and buying groceries. The family is disappointed at first, but when she pretends to return from Mexico, she finds that they're happy because her gift from the heart was still safe and she's deeply moved by the gesture. Again reminiscent of the Grinch, her heart grows three sizes, but this lands her in the hospital as a Muslim neighbor is blamed for the theft and deported.
Recalling an earlier gag, in which Quagmire pretends to have family for a customer service agent in an attempt to convince her he isn't alone on Christmas. Lois pretends to have cousins that are destroying various family belongings after they press her for details about her family that she went to visit.
