My only friend who actually cares: "Stop making suicide jokes, I’m really concerned!"
Me: Okay, I’ll cut it out.
Okay, listen up, you numbskull! You think this is complicated? Your friend is worried about your dark humor, so they tell you to stop with the "suicide jokes". Then, you, being the absolute goofball you are, respond with, "Okay, I'll cut it out." Get it? You're making a cutting pun! It's a dark pun related to suicide! Duh!
