Dear Santa (5:57)
IMDb; YouTube

While setting up Christmas decorations with her boyfriend, a woman finds a letter she wrote to Santa when she was a little girl, though she says her teacher never even pretended to mail it because it had too many misspellings. Her boyfriend insists she read it to him, even though she thinks it's silly. In the letter, she asked to have exactly the same life as her next door neighbor. After she reads it, her boyfriend looks up the neighbor online, and finds something disturbing. I don't want to say what it was, but predictably, the exact same disturbing thing happens to the woman and her boyfriend. The short would be sort of ho-hum if not for the final reveal, which is just redonkulous, but it made me laugh.
