What did the fish say before he hit the wall? -- "Oh, dam."
The Fish and the Wall
Categories
Explanation
Experiment
The humor comes from the pun on the word "dam." It sounds like the swear word "damn" which a fish might say after bumping into a wall, but it's also a wall that's made of dam, which a fish might encounter in the river. It's a play on words, making it a classic dad-joke type of humor.
