Large Mysterious Fish Eats a Duck is a screamer video uploaded by YouTube user antirealm on June 4, 2006. It shows ducks swimming in a pond for 8 seconds, while playing a short clip of the song "Blackbird" by The Beatles. At 9 seconds in, a person wearing a mask jumps in front of the camera and screams, with the same scream sound effect used in the K-fee commercials.
