SpongeBob Dub

Spongebob Dub is a screamer that was published on YouTube on June 13th, 2008. The video starts off as a regular Spongebob dub at the time, as a scene from the episode Club Spongebob plays, albeit dubbed with coarse language. At around 0:19, a picture of the clown from IT shows up with a loud screech (actually the K-Fee scream reversed). After that, text appears on the screen saying "Turn Around!"
