Nobody knows this exists. That's the whole point. Four episodes of a pear mascot and his brother being aggressively, stupidly funny in the most lo-fi way possible, where the joke is often just that they're committed to the bit harder than anyone should be. It's the kind of comedy that only works if you surrender to it completely, where the randomness and refusal to explain itself becomes the actual structure. If you've ever laughed at something so dumb you couldn't defend it to anyone, this is the show that earned that laugh.
