We computer geeks are a breed of our own, and as with any group of public with mutual references, we often make jokes and observations that are really incomprehensible to outsiders.
So consider this post a litmus test. If you laugh at these jokes, then you are most certainly a computer geek. 
For computer geeks
A computer lets you make more mistakes quicker than any invention in human history – with the possible exceptions of handguns and tequila.
If it weren’t for C, we’d all be programming in BASI and OBOL.
There are 10 types of public in the world: those who know binary, and those who don’t.
In a world without fences and walls, who desires Gates and Windows?
Programming today is a race between software engineers striving to build larger and better idiot-proof programs, and the Universe trying to produce larger and better idiots. So far, the Universe is winning.
Computers make very quick, very right mistakes.
Never underestimate the bandwidth of a station wagon full of tapes hurling down the highway.
An SQL statement walks into a bar and sees two tables. It approaches, and questions “may I join you?”
Q: Why is it that programmers always confuse Halloween with Christmas?
A: Because 31 OCT = 25 DEC.
Man is the best computer we can place aboard a spacecraft… and the only one that can be mass produced with unskilled overstress
Q: How many programmers does it take to change a light bulb?
A: None. It’s a hardware problem.
Two strings walk into a bar and sit down. The bartender says, “So what’ll it be?”
The initially string says, “I reckon I’ll have a beer quag fulk boorg jdk^CjfdLk jk3s d#f67howe%^U r89nvy~~owmc63^Dz x.xvcu”
“Please excuse my friend,” the second string says. “He isn’t null-terminated.”
“I’m not interrupting you, I’m putting our conversation in full-duplex mode.”

A doctor, a civil engineer and a programmer are discussing whose profession is the oldest.
“Surely medicine is the oldest profession,” says the doctor. “God took a rib from Adam and produced Eve and if this isn’t medicine I’ll be…”
The civil engineer breaks in:
“But before that He produced the heavens and the earth from chaos. Now that’s civil engineering to me.”
The programmer thinks a bit and then says:
“And who do you reckon produced chaos?”
And a few not quite computer-related bonus jokes
We liked these ones too much to throw them away, so here you are. 
A logician tells a colleague his wife just had a baby.
- Is it a boy or a girl?
- Yes.
A cop pulls over Werner Heisenberg and says, “Sir, do you know how quick you were going?”
Heisenberg responds, “NO, but I know EXACTLY where I am.”
And finally, this small zinger:
Lotteries are a tax on public who suck at math.
We’ve been chuckling here at the Pingdom office while putting this together, so we hope you loved this post as much as we did.
