Let me hear your best knock-knock joke.

The best knock-knock joke I saw was in written form and a text. Someone DM'd someone knock-knock and the other person was like, who's there? And then they were like, you can no longer. And then they were like, you can no longer who? And then they blocked him. and it said you can no longer message this person.

Knock knock, who's there banana? Banana who? I'ma bend down your banana.
