How the Grinch Stole Christmas! (1966)

The original How the Grinch Stole Christmas is shown on the TV on Christmas Eve night when they take grandmas stockings off and hang them on the fireplace.

As the story of "Cinco de Quatro" is explained, a young Lucille Bluth and George Sr. look out over the city as the narrator reads, "You see the Hispanics of Newport liked Cinco a lot; But high up on Coast Highway, Lucille Bluth did not. And then Lucille had a horrible thought; A thought that was thoughtless and better to not. What if, she thought, with a sneering grin, 'Next year, what if the party didn't even begin'". This is a parody of the Dr. Seuss story, 'How the Grinch Stole Christmas'.

The beginning of this episode shows different Christmas movie scenes - Family Guy style.

Dexter says the the psychiatrist, "You're a mean one, Mr. Shrink" which is a reference to a song from the movie with the lyric, "You're a mean one, Mr. Grinch."

Someone comes out dressed in a Grinch costume for the winter holiday ice skating performance.

Leonard, Penny and Sheldon watch this movie before trimming their Christmas tree. Penny says she tears up every time she sees the Grinch's heart grow to three times its size.
