The video acts as a normal "subliminal message" video, using an image of the SpongeBob episode "Mermaid Man and Barnacle Boy II". After a close-up of SpongeBob's teeth, the video jokes that the viewer thought it was a screamer. However, the same face from 'Large Mysterious Fish Eats a Duck" pops up with the same scream.
