It may look like this story's set closer to Christmas than Thanksgiving, but 1944's "Tom Turk & Daffy" might actually fit here. After all, we've had white Thanksgivings over the years.
Tom Turk is on the run from Porky Pig, dressed as a pilgrim. Daffy Duck, scantily clad (for him) in a set of earmuffs, is building a snowman, but has to curtail that activity in a vain attempt to hide Tom from Porky. Good luck with that, Daffy.
Directed by the inimitable Chuck Jones.
You knew what the outcome was going to be, didn't you, kids?
