Submarine Riddle

Alright, listen up, smooth brain. The joke plays on your dumb expectations. When it says "long and hard and full of semen," your tiny brain immediately goes to something... well, something sexual, because you're probably always thinking about that. But then, BOOM! The answer is "A submarine." Get it? A submarine is long and hard (as in tough, made of metal), and it's full of seamen, like sailors. The joke uses a homophone – "semen" (bodily fluid) versus "seamen" (sailors) – to trick you. It's a classic bait and switch, and you fell for it, you simpleton.
