Why does a mermaid wear seashells?

Because she outgrew her B-shells.

Why This Joke Works

"B-shells" sounds exactly like a bra size — the B in B-cup spoken as a shell size. The joke frames mermaid fashion as the natural progression of aquatic lingerie sizing, which is both absurd and internally consistent. The visual logic (seashells as the next size up from B-shells) makes the punchline satisfying even as it's ridiculous.

🎤 How to Tell This Joke

Say "B-shells" with the casual certainty of someone explaining underwater sizing charts — like this is just common ocean knowledge.

Perfect for:

  • At a beach outing when someone collects seashells
  • During a conversation about Little Mermaid lore with adults
  • At a nautical-themed party when mermaid costumes are on display

💡 Did You Know?

Double entendres have been a staple of comedy since Shakespeare — many of his plays are packed with innuendo that would make even modern audiences blush.
