On that note – I think that ST:TNG totally killed the “AI’s don’t get humor” joke. There were times I wanted to punch Data in the face until he segfaults – and I didn’t even watch that show regularly or anything. It just seems that every time that show is on TV I see the damn android failing hard at trying to be more human.

So any time there is a storyline about an AI learning human things like humor, compassion or beauty I get flashback of Data being annoying again. Sigh…

Math-based jokes usually suck. These are no exception.

What’s the square root of -69?
I 8 something.

All my friends are mathematical: they’re either irrational or imaginary.

And from Robert Heinlein, the setup is a guy is explaining humor to an AI.
Guy: “Tell a joke once, you’re a wit. Tell the same joke twice, you’re a half-wit.”
Computer: “Geometric progression?”

Here’s one for the English nerds:

I’m incredible.”

You mean like this one. It brings me back to our Fundamentals of Programming Class we took

On the line of webcomics, PHD Comics are also quite funny. I also like Hackles, but it is no longer updated.

A chemist, a physicist and an economist are stranded on a desert island with nothing to eat when one day a pallet of tinned food washes up on the beach. The chemist says “Well, I can collect some compounds from the island to make a caustic paste, and we can burn the tins open to get to the food.”

The physicist says “That’s too dangerous, and it could adversely affect the food. I can rig up an armature with some wood and a couple of rocks, and we can break the tins open.”

The economist says “You’re both thinking too hard. Opening these tins is simple: First, assume you have a can opener…”

@Craig Heh… We could essentially post every xkcd strip here. :) They are all awesome.

An economist, a logician and a mathematician are on a train from England to Scotland together, shortly after they cross the border they see a brown cow in a field near the train tracks.

The economist says “Look, the cows in Scotland are brown”
The logician says “At least one of the cows in Scotland are brown”
and the mathematician says “There is at least one cow in Scotland, at least one side of which is brown”
