its dryness, it acquires an attractive quality.

(a special case of irony)

Drei Bier?

For the last 40(?) years, a very popular brand of Beer in japan
is Asahi ["Super Dry"] beer.

an apparel and bag maker in the UK copied it,
and last year (?) there was a humorous twist because
these brazen copycat Brits tried to sue the original people.

No, still not clear. Where did these rules ("can't say yes, because...")
come from? Is the joke about the barman asking all three as a group, but
them having to answer as individuals? And they're not allowed to consult
before answering collectively? Maybe a joke about logicians'

| = or, & = and.
In C: | is bitwise or, || is logical or, etc.

Sometimes other symbols are used, V for OR and something like an
uppercase Greek lambda for AND. Or the other way round. No, I

It uses the "|" character to indicate Boolean "or".

Presumably this is derived from the "|" operator in the C programming

(Maybe you're thinking that if one of them meant 'no', they could have said
'no', because the maximum amount then possible would be 2. But that
requires further assumptions - that they all knew what they wanted, that
each one only wanted one drink, and more importantly that each one - or at

This one reminds me of one I heard years ago.

A mathematician, a physicist, and an engineer were travelling through
Scotland when they saw a black sheep through the window of the train.

"Aha," says the engineer, "I see that Scottish sheep are black."

"Hmm," says the physicist, "You mean that some Scottish sheep are black."

"No," says the mathematician, "All we know is that there is at least one
sheep in Scotland, and that it is black on at least one side."

The sheep joke that immediately springs to my mind is both racist and

A medico, an engineer, and a lawyer were arguing over which was the

"The Bible tells us that God took one of Adam's ribs to make a woman",
said the doctor. "That's a medical procedure."

"Yes", said the engineer. "But before that, God produced order out of
chaos. That's an engineering job."

For some reason, this reminded me of the waitress walking by a table
with three fellows talking.

The first fellow says "I think it's spelled "Woom".
The second says "No... it's more likely "whoom".
The third says "I'm pretty sure it's "whoomb".

The waitress leans over and says "Gentlemen, it's definitely "womb".

The three fellow glance around at each other, then one turns to the
waitress and says "Well, I'm almost certain that you've never heard an

That misdirection is part of the puzzle (which I didn't get the first
time
I saw it). But they're logicians, which is a clue that ordinary
interpretation doesn't work.

I think this one can be worked out if it's presented as a puzzle,
ending "How did he know?" In that case "I don't know" can't
mean "I'm still deciding." It has to mean "I know what I want, but
I don't know what the others want." For the third logician to
answer confidently, he has to be able to assume that the other
two know what they want, but three people walking into a bar
together might know each other that well.

No, because each one is answering the question regarding '3', and the only
individual choice that can determine the yes/no outcome for '3' is 'no'. If
one doesn't want it, then the group can't want 3.
But that requires some other assumptions, as mentioned earlier.

rather than "don't know".

No, because each one is answering the question regarding '3', and the only
individual choice that can determine the yes/no outcome for '3' is 'no'.
If one doesn't want it, then the group can't want 3.
But that requires some other assumptions, as mentioned earlier.

The problem with finding 'the boolean expression' is that different moments
of the story are modeled by different expressions. This isn't a single
statement, it's a story.

Also that there are other kinds of inference in the
problem, namely epistemological and numerical. They
could be included in a formal system that used Boolean
logic--for instance, "I don't know" would be a
proposition rather than a third possible value. If
someone were really, really bored.

Kommen drei Logiker in eine Bar. Der Kellner fragt: "Na, was
darfs sein, die Herren? Drei Bier?" Sagt der erste Logiker
"Ich weiß nicht", der zweite auch "Ich weiß nicht" und der
Dritte sagt "Ja"
------ is this funny? i don't really get it.

0 | 0 | 1 = 1, in Boolean logic.

True but irrelevant.
~0 & ~0 & 1 = 1 is the boolean logic that applies.

What do you mean by ~? Not? How is don't know a not.

~ is indeed not.
Saying "don't know" is the *exclusion* of "no" as a possible state,
because if "no" was this guy's intention he would have correctly
answered "no" rather than "don't know".

Similarly, if "yes" was his intention then he would have answered "yes"
rather than "don't know".

False. If guys 1 and 2, the ones who say "don't know" do want a beer,
then they still haven't got a clue if all three of them want a beer,
and therefore cannot confidently answer "yes". "Don't know" is the only
honest answer they can respond.

I Dutch and German, certain native words do not get a plural form with
non-unity numeral. 10 meter (not 'meters'), 6 kilo(gram), 100 m2
(vierkante meter), 1 atmosfeer, 10 atmosfeer/bar/pascal, etc. 15 kW,
kilowatt. But '20 graden' (not 'graad'), etc.

Why? I don't know. Just a convertion. Language is a collection of
habit, of old traditions.
