Knock Knock

Knock Knock is a girl in Little Lamplight. She's the twin sister of Knick Knack and changed her name from Sue to Knock Knock as Knock Knock and Knick Knack sounded better than Knick Knack and Sue. Her role in the community is to be in charge of "morale", a job description that includes knock knock jokes and keeping the peace as an officer of the law.

She's the only character in Little Lamplight who seems to have respect for the Lone Wanderer, and tries learning stories and jokes as much as she can. She found a book (Vault Boy's Big Book of Jokes) to help her with jokes, but these have since then gotten old, and she seems to want to know more.

Talk to Knock Knock enough and you can tell her your story; regardless of your karma you can tell her a good, neutral or evil version. Whatever you tell her she will precede to tell it back to every other Lamplighter she comes across.
