Creator: David Hasselhoff

SpongeBob: Who're you?
David Hasselhoff: I'm David Hasselhoff.
SpongeBob and Patrick: Hooray!

The Hoff needs no explanation. He simply is the embodiment of Knight Rider and Baywatch.

Rumors of links between him and a man known simply as "Kane" (due to very subtle similarities in their situations) remain unsubstantiated.

He was Nick Fury long before Samuel L. Jackson.

Also, the Germans love him, really.
