The jumping spider, scorpion, featureless polar bear, meta-explainer, and narrator walk into a bar.

"What is this?" asks the frog. "All these animals are coming into the bar. What do they all have in common?"

The spider keeps coming.

"They're all knock-knock jokes!" says a voice in the distance.

The frog stares into the distance and sees the featureless polar bear.

"Oh my God," mutters the frog to himself. "They're all my jokes."

The bar smells like rotting flesh.
