Freakazoid attempts to get back to the real world by mimicking Dorothy from 'The Wizard Of Oz' and saying "There's no place like home" while clicking his heels. Cosgrove quotes the Cowardly Lion when he says "I do believe in spooks. I do. I do."
The shot of Freakazoid running toward the camera to avoid the pterodactyl is a reference to a famous scene from Alfred Hitchcock's 'North By Northwest' (in that case it was Cary Grant and a biplane).
