Skeletons tend to be portrayed as calm in jokes and memes because their nature allows for a punny contrast: they have no nerves or skin to worry about, so “nothing gets under their skin.” In humor, this creates a light, absurd image of unflappability that audiences find playful and silly. Brief take on the humor:

• Wordplay: The phrase “nothing gets under their skin” is a common skull-themed pun, since skeletons lack skin.
• Visual continuity: Skeletons are often shown in spooky or Halloween contexts where calm, unbothered vibes feel playful rather than scary.
• Universal gag: Because the joke hinges on a harmless bodily fact (they’re dead and missing skin), it’s easy to share and understand across ages.

If you want to use or adapt the joke:

• Classic line: “Why are skeletons so calm? Because nothing gets under their skin.”
• Alternate punchlines you can try:
  • “They don’t have nerves about anything.”
  • “They’re dead calm.”
  • “They’ve got a bone-dry sense of humor.”
