Is this a Nitro crossover?

yes, apparantly the plot revolves around a bunch of people who get strange urges to go around spearing people then yell "who's next."

Could the Goldburg in the title possibly be Rube Goldburg? If so, this episode will probably be a hoot. Rube was famous for drawings of elaborate devices that perform simple tasks. One I particulaly remember involved about 18 different moving parts, beginning with a swinging log and ending with a glass of freshly squeezed OJ.

I meant Goldberg, of course. There are some of his drawings are at www.rubegoldberg.com.

Yes.
