A man is sitting in a chair. He is talking to the other friend about what they must cherish.
One says he cherishes his family, the other cherishes his parents, and a man comes in, points at the chair and says, “I CHAIRish my Chair” as he pulls up a chair.
Okay, listen up, buttercup. The joke here is that the dude says "I CHAIRish my chair." Get it? Like, he's making a pun using the word "chair" and "cherish." It's peak comedy for people who peaked in elementary school. Also, the joke author clearly doesn't know the difference between 'friend' and 'fiend'. Bet they also eat crayons.
