This one is a bit tougher. What is black when you buy it, red when you use it, and grey when you throw it away?

These things to be any good should only have a single answer.

Did I say the other answers were wrong?

Good thing nobody puts you in control of what what is "good" or not, or this world would be in alot of trouble.

Ok to keep it moving the answer is CHARCOAL

Can you name three consecutive days without using the words Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, or Sunday?

Yesterday, Today, Tomorrow.

Good Friday, Easter Saturday, Easter Sunday? Probably a stupid guess

Gold star & elephant stamp for Casper! bindi I see you have the words Friday, Saturday & Sunday in your answer lol, try again

Last one...

This is an unusual paragraph. I'm curious how quickly you can find out what is so unusual about it. It looks so plain you would think nothing was wrong with it. In fact, nothing is wrong with it! It is unusual though. Study it, and think about it, but you still may not find anything odd. But if you work at it a bit, you might find out.

Done, next!

Given that E is the most commonly used letter in the English language and it is not used once in that entire paragraph, I would say thats pretty unusual.

Bingo - your turn

nat_daly · 31-08-2005, 06:39 PM

Thought id chuck a common one in here..lol

A man is walking along a street full of murderer's residences, in a damp wet environment.. There are no lights on in the whole neighbourhood, and the man is wearing a black suit, while walking allong in the middle of the road. A car comes around the corner with no lights on, and instead of running over and killing the man, the car stops and drives around him.. why is this??

id tell more but i only got ones my mates made up..:P
casper your turn..

Casper · 31-08-2005, 06:46 PM

I dont have any

nat_daly · 31-08-2005, 06:48 PM

hah oh well.. at least your answering them..

outback_ute · 31-08-2005, 06:49 PM

This one has whiskers on it, but here goes

A man is sitting in his house, which has 4 walls and a window in each wall. Whichever window he looks out of he is facing south. A bear walks past - what colour is the bear?

White. Has to be a Polar bear if he is ar the extreame north (opposite to south) pole.

There is an island filled with grass and trees and plants. The only inhabitants are 100 lions and 1 sheep.
The lions are special:
1) They are infinitely logical, smart, and completely aware of their surroundings.
2) They can survive by just eating grass (and there is an infinite amount of grass on the island).
3) They prefer of course to eat sheep.
4) Their only food options are grass or sheep.

Now, here's the kicker:

5) If a Lion eats a sheep he TURNS into a Sheep (and could then be eaten by other lions).
6) A lion would rather eat grass all his life than be eaten by another lion (after he turned into a sheep).

Assumptions:
1) Assume that one lion is closest to the sheep and will get to it before all others. Assume that there is never an issue with who gets to the sheep first. The issue is whether the first lion will get eaten by other lions afterwards or not.
2) The sheep cannot get away from the lion if the lion decides to eat it.
3) Do not assume anything that hasn't been stated above.

So now the question:
Will that one sheep get eaten or not and why?

Hint
There are two hints. The first one will really be just that - a small hint. The second one is a BIG one, and could very well give it away, so don't read it if you don't want to:

Hint 1) Use math induction.
Hint 2) Consider the scenario where there is only one lion and one sheep. What would happen? Now take the next step.

andrew_smith_84 · 31-08-2005, 07:14 PM

no, the lion that turns into a sheep could end up being alone with another lion and get eaten?

Will that one sheep get eaten or not and why?

Answer
The sheep would remain untouched.

In fact, the sheep would remain untouched if there is an even number of lions on the island, and would be eaten immediately if there is an odd number of lions on the island.

Here's the reasoning:
Consider a scenario with just one lion and one sheep: The lion will eat the sheep. Why? Because after he eats it and turns into a sheep himself, there aren't any lions on the island to eat him, so he is happy.

Now look at a scenario with 2 lions and 1 sheep. Here the sheep would remain unharmed. Why? Because if any one of them eats it, and turns into a sheep himself, he knows that he awaits certain death because he will then be a sheep and the other lion will be the only lion on the island and nothing will stop him from eating the sheep.

So now we know for a fact 1 lion and 1 sheep - sheep gets eaten. 2 lions and 1 sheep - sheep doesn't get eaten.
We can now make a conclusion about 3 lions and 1 sheep: the sheep will definitely be eaten, because the lion that eats it will know that by eating he leaves behind 2 lions and 1 sheep (himself). And as we already know 2 lions and 1 sheep is a situation where the sheep survives.

You can use the same logic to go on to 4 lions and 1 sheep, and then all the way to 100 or 1000, but it will always be true that with an odd number of lions the sheep gets eaten and with an even number the sheep doesn't.

But just one vegitarian lion could throw the whole shebang out. Even a lion that liked beef but didn't care for lamb.

A vegetarian lion could prefer sheep but have sufficient conscience to eat grass instead as a lionitarian gesture!
