Here's my next riddle:
Consider a list of 2000 statements:
1) Exactly one statement on this list is false.
2) Exactly two statements on this list are false.
3) Exactly three statements on this list are false.
. . .
2000) Exactly 2000 statements on this list are false.
Which statements are true and which are false?
I have 2 guesses. 1. All of them are true 2. 2000) Exactly 2000 states on this list are false ( Meaning that one is true )
If you think about your answers a little more, you'll see that neither of them can be correct. Let's look at them one by one:
1. All of them are true
This is impossible, since every sentence contradicts the other. In otherwords, take statements 1 and 2 together. The first says "exactly 1 statement is false" and the second says "exactly 2 statements are false." Both of these statements obviously cannot be true.
2. Exactly 2000 states on this list are false ( Meaning that one is true )
If that were the case, then statement 2000 would be in fact true, and therefore 2000 statements wouldn't be false--1999 would. (This should be a hint!)

The statement \"Exactly 1999 statements in this list are false.\" is the only true statement. It is one statement out of the 2000 that are true, and thus 2000-1 = 1999 statements are false. :-D
Here's my next riddle, which deviates in style from most of my logic-requiring riddles:
You walk into a room in which there are three primates: a chimpanzee, an orangutan, and a gorilla. The chimpanzee is holding a banana in each hand, the orangutan is holding a big stick, and the gorilla is holding nothing. Which primate in the room is the smartest?
A man goes home at 4pm and see his wife cooking, he then goes take a nap and when he woke up (at 7pm) a marvelous dinner was prepared. At 10 pm they go to bed. In the morning at 7am, he killed her. Why?

your riddles could have potentionally more answers but i try a shot :P
the man came home and took the nap, the woman took a break and had sex with another man. But then she couldn't explain to the man if he found out so she killed the man and put him in the dinner. By the time the man was awake she was done with some marvelous dinner! so they slept. the man woke up in the middle of the night and saw some clothes that the wife had forgotten to put away. so seeing this he knew so was not being honest and he couldn't live with this and killed her xD
nr. 2
the woman was done preparing the food but didn't know it some parts of it were poison and she ate that part of the food and died later
nr.3
the man and wife were at dinner suddenly the woman has to go to the toilet and the man who h8es his wife puts some poison in her drinks/food and sit's back and when the woman returns she eats it and dies later
nr4.
the woman was IMMENSE she could barely sit in one chair well actually she needed two chairs to sit on. She ate and ate and ate and ate untill she was stuffed. so after eating she went to bed. But her body couldn't keep up with the huge immense fat so her belly burst open and she got an heartattack of too much fat

you are a prisoner in a foreign land. your fate will be determined by a little game. there are two jars, one with 50 white marbles, and one with 50 black marbles. at this point, you are allowed to redistribute the marbles however you wish (e.g. swap a black marble with a white marble, etc.): the only requirement is that after you are done with the redistribution, every marble must be in one of the two jars. afterwards, both jars will be shaken up, and you will be blindfolded and presented with one of the jars at random. then you pick one marble out of the jar given to you. if the marble you pull out is white, you live; if black, you die. how should you redistribute the marbles to maximize the probability that you live; what is this maximum probability (roughly)?
You can make your probability of success very very close to 75% (but not quite). In one jar, you take out everything but leave one white marble. The second contains all of the rest of the marbles.
The formula for the total probability of life is:
P(jar1)*P(live from jar1) + P(jar2)*P(live from jar2).
With my above scenario, picking jar1 has a 50% chance (you can piece either jar equally likely). If you pick jar1, you are guaranteed to live, since there is only one marble, namely the white marble.
If you pick jar 2 (also a 50% chance), you have a roughly 50% chance--in it are 50 black marbles and 49 white marbles (so in actuality, the probability is 49%).
Therefore the total probability is 0.5 * 1 + 0.5 * 0.49 = 0.745
...=74.5% chance of surviving!
I'll take these odds over randomness any day.
My next riddle is slightly more difficult, but it follows the same logic lines as my previous 'x statements are false' riddle. It's a great riddle:
There is an island of monks where everyone has either brown eyes or red eyes. Monks who have red eyes are cursed, and are supposed to commit suicide at midnight. However, no one ever talks about what color eyes they have, because the monks have a vow of silence. Also, there are no reflective surfaces on the whole island. Thus, no one knows their own eye color; they can only see the eye colors of other people, and not say anything about them. Life goes on, with brown-eyed monks and red-eyed monks living happily together in peace, and no one ever committing suicide. Then one day a tourist visits the island monastery, and, not knowing that he's not supposed to talk about eyes, he states the observation "At least one of you has red eyes." Having acquired this new information, something dramatic happens among the monks. What happens?
We are very little creatures; all of us have different features. One of us in glass is set; one of us you'll find in jet. Another you may see in tin, and a fourth is boxed within. If the fifth you should pursue, it can never fly from you. What are we?
The Vowels A, E, I, O and U
I am two-faced but bear only one, I have no legs but travel widely. Men spill much blood over me, kings leave there imprint on me. I have greatest power when given away, yet lust for me keeps me locked away. What am I?
A Coin
I dance four feet to ev'ry line, with A and A I try to rhyme. And B and B make couples two, the answer my friend stands in front of you.
This Riddle!
Often held but never touched, always wet but never rusts, often bites but seldom bit, to use me well you must have wit.
Your Tongue
Break it and it is better, immediately set and harder to break again.
A Record (not the musical kind....)
We love it more than life. We fear it more than death. The wealthy want for it. The poor have it in plenty.
Nothing
What can run, but never walks, has a mouth but never talks, has a bed but never sleeps, has a head but never weeps?
A River
Feed me and I live, Give me drink and I die. What am i?
A Fire
This is light as a feather, yet no man can hold it for long.
One's Breath
What has eyes, yet cannot see?

I'll stop now and if any of you got some right I say Thankee-sai, You speak true.
Blaine is a Pain and that is the Truth.
Most of these riddles come from Stephen King's Novel, The Dark Tower: Wizard and Glass. The fourth book in a brilliant series READ THEM.

I think they all commit suicide
if more than one monk has red eyes, then they would not need the tourist to tell them anything. Therefore, given the facts presented in the riddle, one monk will commit suicide on the first night. Period. If more than one monk had red eyes, the suicide would’ve taken place before the tourist had a chance to tell them anything.
