Water Jokes

With water being one of the key ingredients of our existence, one would expect that many jokes have been written about it. Here is a collection. Some of these are “wastewater” jokes, since I use them in my class that covers both water and wastewater. Most of these are found on multiple Internet sites and the original authors are hard to pin down; so I don’t claim to have written them all (and maybe I won’t claim the few that I have written!)

Prawns, Cod, and Sharks

(Shared by Chandler Peterson)

In the shark-infested waters of the Caribbean, two prawns called Justin and Christian are discussing the pressures of being a preyed-upon prawn. “I hate being a prawn,” says Justin. “I wish I were a shark.” Suddenly, a mysterious cod appears. “Your wish is granted,” he says. Instantly, Justin becomes a shark. Horrified, Christian swims away, afraid his former friend might eat him. As time passes, Christian continues to avoid Justin, leaving the shrimp-turned-maneater lonely and frustrated. So when he bumps into the cod again, he begs the mysterious fish to change him back. Lo and behold, Justin is turned back into a prawn. With tears of joy in his tiny little eyes, he swims back to the reef to seek out Christian. As he approaches, he shouts out: “It’s me, Justin, your old friend. I’ve changed… I’ve found Cod. I’m a prawn again, Christian.”

Ant Gender

(Submitted as a bonus question on an exam by Matthew Burris)

My dog Lassie once spent an hour trying to explain to me that Timmy had fallen down a deep cylindrical hole full of water.

Burning House

A mathematician and a physicist were asked the following question: Suppose you walked by a burning house and saw a hydrant and a hose not connected to the hydrant. What would you do?

Physicist: I would attach the hose to the hydrant, turn on the water, and put out the fire.
Mathematician: I would attach the hose to the hydrant, turn on the water, and put out the fire.

Then they were asked this question: Suppose you walked by a house and saw a hose connected to a hydrant. What would you do?

Physicist: I would keep walking, as there is no problem to solve.
Mathematician: I would disconnect the hose from the hydrant and set the house on fire, reducing the problem to a previously solved form.

Cold Water

A guy was visiting his brother for lunch. He looked at his plate and asked his brother, “Are these plates clean?” The brother said, “They’re as clean as Cold Water can get them.” Later for dinner it was similar. “Are you sure these plates are clean?” “Like I said, clean as Cold Water can get them.” Later they were headed to town and went out the front door. The brother tripped over his dog lying in front of the door and said, “Get out of the way, Cold Water!”


You all know the chemical formula for water, H2O. What is H2O2? Hydrogen peroxide, which is not very stable, but is highly reactive. What is H2O3? It doesn’t exist. The electronic structures around hydrogen and oxygen don’t allow this molecule to form and be stable. So what is H2O4? Drinking, bathing, swimming, etc.

Paint Thinners

Two men contracted to paint a small community church. Being very frugal (cheap), they pinched and scraped to spend the absolute minimum on materials. Then, when they were only partway through the job, they realized they didn’t have enough paint to finish. They decided they would just dilute the water-based paint they were using so that it would last longer. The painters had just about gotten to the top of the steeple, when, all of a sudden, the sky darkened, and the rain started to pour down. As the paint streamed down the sides of the church, a voice boomed from the heavens: “Repaint, you thinners! Repaint, and thin no more!”

Cherry Tree

A man has three sons. One day he calls them together and says, “Boys. One of you knocked over the outhouse. I want you to tell me who did it. Jim, did you do it?” “No, Dad.” “Frank?” “No, Dad.” “Harry?” “No, Dad.” “OK boys. Let me tell you a story. When George Washington was a little boy he chopped down his dad’s cherry tree. When his dad asked him about it George said, ‘Father, I can not tell a lie. I chopped down your cherry tree.’ And his dad loved him and praised him for being honest and telling the truth. So boys, let me ask you again. Did you knock over the outhouse?” Harry stood up and said, “Dad, I can not tell a lie. I knocked down the outhouse.” The father grabbed the boy and began spanking him vigorously. Harry said, “But Dad, I thought you said George Washington’s dad praised his son for telling the truth; he didn’t beat him because of it!” “Yes, son, but George Washington’s dad wasn’t sitting in the cherry tree!”

Bring Me My Red Shirt

A treasure ship was on its way back to port. About halfway there, it was approached by a pirate, skull and crossbones waving in the breeze.

“Captain, captain, what do we do?” asked the first mate.

“First mate,” said the captain, “go to my cabin, open my sea
chest, and bring me my red shirt.” The first mate did so.

Wearing his bright red shirt, the captain exhorted his crew to
fight. So inspiring was he, in fact, that the pirate ship was repelled
without casualties.

A few days later, the ship was again approached, this time by two
pirate sloops!

“Captain, captain, what should we do?”

“First mate, bring me my red shirt!”

The crew, emboldened by their fearless captain, fought heroically, and
managed to defeat both boarding parties, though they took many
casualties. That night, the survivors had a great celebration. The
first mate asked the captain the secret of his bright red shirt.

“It’s simple, first mate. If I am wounded, the blood does not
show, and the crew continues to fight without fear.”

A week passed, and they were nearing their home port, when
suddenly the lookout cried that ten ships of the enemy’s armada were approaching!

“Captain, captain, we’re in terrible trouble, what do we do?”
The first mate looked expectantly at the miracle worker.

Pale with fear, the captain commanded, “First mate…. bring me my
brown pants!”

(This is a wastewater joke, …sort of!)

“No!” Replied the dad. “You already had your chance. You know I told you not to keep delaying bedtime by asking for things. Now go to sleep!”

A few minutes later the son called out again, “Dad, I’m really thirsty! Can you bring me a glass of water?”

“No! And if you keep asking I’m going to come in there and spank you!”
