Klaatu Verata Necto 

These are the spoken words required to retrieve the Necronomicon. If you do not speak the words "Klaatu Verata Necto" before picking up the Necronomicon, there will be hell to pay.

Ash attempts to pickup the Necronomicon, and fails to say the words "Klaatu Verata Necto". The demons below the earth wake and attempt to destroy Middle Earth. (see the movie "Army of Darkness" with Bruce Campbell).

Neco Coneco 

A fictional toy that appeared in the manga Azumanga Daioh. It often comes in the form of a small white kitten sitting on the head of a white cat, but also comes in different forms such as sleeping cats or Iriomote cats (An endangered species only found on the island of Iriomote in Japan) The character Sakaki is particularly fond of the brand.

The name "Neco Coneco" comes from the Japanese name, "Neko Koneko" which literally translates to "Cat Kitten." The romanization of its Japanese name also sounds like "Connected Cat."

Girl 1: I just love Neco Coneco! I wish they were real.....
Girl 2: Isn't that those cat dolls from Azumanga Daioh? It's a plush, right? Why don't you sew one?
Girl 1: That's a great idea! Too bad I can't sew....
