知らんのか
A [[meme]] originating from a scene in [[Space Adventure Cobra]]. It involves a character anticipating something happening, another character asking what will happen afterwards, and receiving an ironic response from the first, punctuated by 知らんのか ("You don't know?"). The meme received a lot of attention in social game circles under the format:

"What happens when maintenance ends?"
"You don't know?"
"That's when maintenance begins."
