Riddle of the Sphinx

English Bowlers
In a bag are five English bowlers: three white ones and two
black ones.
Three men are standing behind each other in front of a wall, all looking
at each other's back with the first one ultimately just seeing the wall. I
randomly grab a bowler from the bag and put one on each head of the men,
taking care that they don't see what color I put on their own head.
After that, I ask the man at the back of the row if he can tell what
color of hat he has on his head. His answer is "No". I then proceed to the
man in front of him and ask him the same question. He also answers "No". I
go further to the first man, the one standing closest to the wall, and also
ask him if he knows what color of hat that he has on his head. Surprisingly
he answers "Yes" and is even right in his knowledge of the color. Can you
also tell me what hat he is wearing?
Bottles
Suppose you're out on the streets in front of an unlimited
water tap and you have two water jars with you: one bottle with a capacity of
three liters and one that can hold five liters.There are no marks on the jars.
Can you fill a bottle with exactly four liters water?
Bridges to Freedom
After more than two years of pain and suffering, you finally
managed to escape from the dungeon in the castle you were held captive. Chased
by that evil man who kept you imprisoned, you must escape out of this castle as
quick as possible. However, to be fully out of his reach, you must cross the
watercanal that is surrounding his castle, 'cause he never leaves his own
territory. There are two bridges you can take to escape to freedom, but beware:
one of the two will not be stable enough to take you to the other side. If you
don't want to end as food for the crocodiles in the cold water down there, you
must make the right choice. Luckily, two twin brothers that both know the
stability of these bridges are standing on the side of freedom. But there is
still one problem: you know that one of these brothers always tells the truth
and that his brother always lies, but you don't know who is who. Unfortunately,
the master of evil is getting closer, so you don't have time for a friendly
conversation. You have only time to pose one question to one of the twins and
then you must run on one of those bridges. What question will you ask?

A physician, a civil engineer, and a computer scientist
were arguing about what was the oldest profession in the world.
The physician remarked, "Well, in the Bible, it says that God created Eve from a
rib taken out of Adam. This clearly required surgery, and so I can rightly
claim that mine is the oldest profession in the world."
The civil engineer interrupted and said, "But even earlier in the book of Genesis, it stated
that God created the order of the heavens and the earth from out of chaos.
This was the first and certainly the most spectacular application of civil
engineering. Therefore, fair doctor, you are wrong: mine is the oldest
profession in the world."
The computer scientist leaned back in his chair, smiled and then said confidently, "Ah, but who do you think created the chaos?"

One night, a Delta twin-engine puddle jumper was flying somewhere above New Jersey. There were five people on board: the pilot,
Michal Jordan, Bill Gates, the Dali Lama, and a hippie. Suddenly, an oxygen
generator exploded loudly in the luggage compartment, and the passenger
cabin began to fill with smoke. The cockpit door opened, and the pilot burst
into the compartment.
"Gentlemen", he began, "I have good news and bad news. The bad news is
that we're about to crash in New Jersey. The good news is that there are
four parachutes, and I have one of them!". With that, the pilot threw open the door and jumped from the plane.
Michael Jordan was on his feet in a flash. "Gentlemen," he said, "I am
the world's greatest athlete. The world needs great athletes. I think the
world's greatest athlete should have a parachute!". With these words, he
grabbed one of the remaining parachutes and hurtled through the door and
into the night.
Bill Gates rose and said, "Gentlemen, I am the world's smartest man. The
world needs smart men. I think the world's smartest man should have a
parachute, too.". He grabbed one and out he jumped.
The Dali Lama and the hippie looked at one another. Finally, the Dali
Lama spoke. "My son," he said, "I have lived a satisfying life and have
known the bliss of True Enlightenment. You have your life ahead of you; you
take a parachute, and I will go down with the plane.".
The hippie smiled and said, "Cool it, pop. The world's smartest man just
jumped out wearing my backpack!".
