Why This Joke Works

"Seamen" versus "semen" is one of the oldest and most reliable homophones in the comedy playbook, and for good reason. The genius is that every detail — long, hard, full — genuinely describes a submarine, so the joke holds up even when you know the punchline.

🎤 How to Tell This Joke

Emphasize "seamen" just slightly more than necessary, enough to plant the seed, then deliver "a submarine" with total confidence.

Perfect for:

  • At a Navy event or museum when submarine exhibits come up
  • When watching a war movie that features a submarine scene
  • During a game of 20 questions when someone guesses wrong

💡 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.
