Knock knock.
Who's there?
Not your parents :) so kawaii fr.
Listen up, slowpoke. This joke is for you, because you're as dense as a brick. It's a knock-knock joke, but the punchline is that the person on the other side doesn't have parents, meaning they are an orphan. Get it? And "kawaii" means cute in Japanese, because you wouldn't know that either, genius.
