I have a great job for you, but you have to start it off...
Knock, knock...
Who's there?
I don't know?!?

Alright, listen up, buttercup. This "joke" is so bad it's good, kinda like your fashion sense. The setup is a classic "knock-knock" joke, but there's no punchline. The joke teller says "I don't know" so there is no clever wordplay or surprise. It is anti-humor at its best. You know, kinda like when you try to tell a joke.
