Fun On Friday #141: Nerd Humour

Apologies in advance for this because a) it's very late an b) it's even more niche than usual.
I came across this joke recently and it occurred to me that its main appeal is to nerdy computer types... like me!

A wife asks her husband, a programmer, "Could you go to the shops and buy one carton of milk, and if they have eggs, get six!"

A short time later the husband comes back with six cartons of milk. The wife asks him, "Why did you buy six cartons of milk?"

He replied, "Well, they had eggs."

So this started me thinking of other computer nerd friendly jokes. Here are the three that came to mind:

There are 10 types of people in the world. Those that get binary and those that don't.

Which reminded me of this one:

Why do Computing Scientists get confused between Halloween and Christmas?

Because 31Oct = 25Dec

And finally, on an unrelated theme:

Helvetica and Times New Roman walk into a bar in the Wild West. The barman shouts, "Hey! I've told you before. We don't serve your type here!"

To which Times New Roman replies, "Oh yeah? How would you like to tell that to the Serif?"

On a scale of one to ten, how bad are they? And more to the point, can you do better? Leave your computer nerd jokes in a comments.
