The letter K-ay

A man in a dark shirt appears on a small television screen with a purple glow, first shown interacting with a large yellow puppet, then reacting with a surprised expression as the word "KKK" appears on screen. The scene cuts to a man and a woman sitting on a couch, eating popcorn, where the man stands up and laughs while the woman looks up in surprise. The video loops between the television screen and the couple's reaction.
