Writing an Ice Joke

My brother-in-law says he’s been working on a joke for a couple years now and it has to do with water. It all started with a punch line that came to him. He thought he had it all worked out and tried it with a friend. It starts with an ice cube. But he messed up the delivery and ruined it. He figures it wasn’t very well thawed out.

Flying Commercial

Passengers on a small commuter plane were waiting for the flight to leave. They were getting a little impatient, but the airport staff assured them that the pilots would be there soon.

Finally, two men dressed in pilot uniforms walked up the aisle. Both wore dark glasses, one was using a seeing-eye dog, and the other was tapping his way up the aisle with a cane. Nervous laughter spread through the cabin but the men entered the cockpit, closed the door, and started up the engines.

The passengers glanced nervously around, searching for some sign that this was just a little practical joke. None was forthcoming. The plane moved faster and faster down the runway, and the people at the windows realized that they were headed straight for the water at the edge of the airport.

As people see the water approaching, panicked screams filled the cabin, but at that moment the plane lifted smoothly into the air. The passengers relaxed and laughed a little sheepishly, and soon they all retreated into their magazines, secure in the knowledge that the plane was in good hands.

In the cockpit, the pilot turned to the co-pilot and said, “You know, Bob, one of these days, they’re gonna scream too late, and we’re all gonna die!”

Skinny Dipping

A man in Florida owned a large farm with a pond in the back. It was a good swimming spot, so he fixed it up nice with a deck, lawn chairs, picnic tables, and some orange and lime trees.

One evening the farmer decided to go down to the pond, as he hadn’t been there for a while, and look it over. He grabbed a five-gallon bucket to bring back some fruit. As he neared the pond, he heard voices shouting and laughing and having fun. As he came closer, he saw it was a bunch of young women skinny-dipping in his pond.

He made the women aware of his presence, and they all went to the deep end. One of the women shouted to him, “We’re not coming out until you leave!” The farmer frowned, “I didn’t come down here to watch you ladies swim naked or make you get out of the pond naked.”

Holding the bucket up he said, “I’m here to feed the alligator.”

Prawns, Cod, and Sharks

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.”

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.

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!”

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!)
