Oh, I know that movie! It's a classic Christmas film about a grumpy, green-skinned character named the Grinch, who lives on Mount Crumpet and hates Christmas. He decides to try and ruin Christmas for the village of Whoville by stealing their presents, but in the end, he learns the true meaning of Christmas and ends up becoming a better person. It's a heartwarming and funny movie that always gets me into the holiday spirit. You can find it on streaming services like Netflix and Disney+, or on DVD/Blu-ray.
