Listen, we know that being an engineer is a serious job. In fact, some may go so far as to say it’s no laughing matter — from buildings to pacemakers, engineers design things that, well, you don’t want to fail. That’s a lot of responsibility! But the truth is, sometimes a little levity is precisely what these essential professionals need. And if you’re an engineer (or have one in your life), engineer jokes and puns could be the fun you’re looking for when you need a break from mentally doom-scrolling the disastrous consequences of what could happen if your work goes wrong. Just file “taking five for a good laugh” under your personal development goals.

Another thing about engineers? They have a sort of — how do we say this? — esoteric brand of humor. Engineers find stuff like patches, programs, updates, and even electricity hilarious. So, if you aren’t in that field, well, some of these jokes might fly over your head. And you know what? That only makes engineer jokes and puns funnier to these professionals. Every joke is basically an inside joke!

So, if you’re an engineer and need a bit of humor to help pull you out of a slump or distract you from a tedious problem-solving session, keep reading for some of the best engineering jokes on the web.

Best Engineer Jokes and Puns


  1. The optimist says, “The glass is half full.”

The pessimist says, “The glass is half empty.” The engineer says, “The glass is twice as big as it needs to be.”

  1. What’s the difference between mechanical engineers and civil engineers?

Mechanical engineers build weapons; civil engineers build targets.

  1. You might be an engineer if…

You window shop at Radio Shack.

  1. The Laws of Engineering:

– Any circuit design must contain at least one part that is obsolete, two parts that are unobtainable, and three parts that are still under development. – Nothing ever gets built on schedule or within budget. A failure will not appear until a unit has passed final inspection. If you can’t fix it — document it. – The primary function of the design engineer is to make things difficult for the fabricator and impossible for the servicemen.

  1. An engineer, a statistician, and a physicist are out hunting. They spot a buck, and each takes a turn to try and bag it.

The physicist goes first. He pulls out his lab book and quickly calculates the trajectory of the bullet, assuming it is a perfect sphere in a vacuum. The bullet falls 20 meters short of the deer. The engineer goes second. He pulls out his engineering pad and book of projectile assumptions. After a few minutes, he’s ready. He takes aim and fires. The bullet lands 20m past the deer. The statistician triumphantly leaps in the air, shouting, “We got it!”

  1. A chemist, a physicist, and a chemical engineer are rafting down a river. They crash the raft onto the bank. They have a supply of canned goods but no can opener.

The chemist tries to erode the can. That doesn’t work. The physicist uses his glasses to focus the sunlight to burn a hole in the can. That doesn’t work either. The chemical engineer stands up and proclaims, “I’ve got it! Assume the can is open!”

  1. Three engineers were gathered together to discuss the possible designers of the human body. One said, “It was a mechanical engineer. Just look at all the joints.”

Another said, “No, it was an electrical engineer. The nervous system has many thousands of electrical connections.” The last said, “Actually, it was a civil engineer. Who else would run a toxic waste pipeline through a recreational area?”

  1. How do you get an engineer to do something you want them to do?

Tell them it’s “impossible.”

  1. A wife asks her husband, an engineer, for a favor.

“Darling, can you please pop out to the store and get a pint of milk? And if they have eggs, get a dozen!” Off the man goes to the shop and, half an hour later, returns with 12 pints of milk.

  1. Engineer No. 1: “I bet you can’t name two structures that can hold water.”

Engineer No. 2: “Well, dam.”

  1. Wind turbine No. 1: “What kind of music do you like?”

Wind turbine No. 2: “I’m a big metal fan.”

  1. An indeterminate beam walks into a bar.

“What can I get ya?” asks the bartender. “Just give me a moment,” replies the beam.

  1. There are 10 types of people in this world: Those who understand binary, and those who don’t.
  2. Before studying engineering, if someone asked me what 1 + 1 is, I would have said 2.

Now, I’d say I’m pretty sure it’s 2, but we’d better make it 3 just to be safe.

  1. What’s the difference between a doctor and an engineer?

A doctor kills people one at a time.

  1. What did the electrical engineer say when he got shocked?

That hertz.

  1. A graduate with a science degree asks, “Why does it work?”

A graduate with an engineering degree asks, “How does it work?” A graduate with an accounting degree asks, “How much will it cost?”

  1. New engineer: “How do you estimate how long a project will take?”

Seasoned engineer: “I add up the time required for each task, then multiply the sum by pi.” New engineer: “Why pi?” Seasoned engineer: “It ensures that all my budgets are irrational.”

  1. What do you give your favorite electrical engineer for their birthday?


  1. A mathematician, a physicist, and an engineer are all trying to find the volume of a yellow bouncy ball.

The mathematician gets his calipers out and measures the diameter, then evaluates the integral. The physicist fetches a bowl of water, drops the ball in, and measures the displacement. The engineer strolls up with book in hand, checks for a serial number, and looks up the volume in his yellow bouncy ball table.

Why won’t you kiss me?” “Look,” said the man. “I’m an engineer. I don’t have time for a girlfriend, but a talking frog — now that’s cool!”
