Scratch

Some sets, such as the set of all teacups, are not members of themselves. Other sets, such as the set of all non-teacups, are members of themselves. Call the set of all sets that are not members of themselves “R.” If R is a member of itself, then by definition it must not be a member of itself. Similarly, if R is not a member of itself, then by definition it must be a member of itself.

O.o It's Russel's Paradox 

Um, 6.5/10...

Consider all of the men in a small town as members of a set. Now imagine that a barber puts up a sign in his shop that reads I shave all those men, and only those men, who do not shave themselves.

Obviously, we can further divide the set of men in this town into two further sets, those who shave themselves, and those who are shaved by the barber. To which set does the barber himself belong?

The barber cannot shave himself, because he has said he shaves only those men who do not shave themselves. Further, he cannot not shave himself, because he shaves all men who do not shave themselves!


lol, I'm a cheatet XD I used google to find it XD

7/10 (I am rating this on evilness)

Answer these questions yes or no, without lying:

1. Will you answer the following statement the same way you answered this one?
2. Are you obsessed with Scratch?

I love paradoxes, Me and my friend made a ton of these at lunch yesterday. I kept on repeating my "Yo mama" one and he yelled Shut up really loud XD

See:
Yo mama is so fat
Well If the other person plays it through thier mind and says the same it says Yo mama is fat, So it could go on forever until someone says like:
"Jack Walton of Chicago and Blonde hair with a scar's mama is fat", Making that more specific

Go down one sentence
Go down two sentences
Go up two sentences
Go up one sentence

CHEATER!!!

5/10, Not really a paradox, how about this one:

A man goes back in time and kills his parents when they were children. But that means that he was never born, so he could never have gone back and killed them in the first place.

This isn't a paradox, though it makes you think.

Suppose you have a bag. Let's assume that each bag can hold five bags, scrunched up or something along those lines.
Now, you start with one bag. Pile five bags into it. So far so good, right?
Now assume that those five bags had five bags packed into them. It's getting cramped, right?
But there's the rule.

I know it's not much, but I think it's worth mentioning.

8/10

I hate thinking about that! It makes me feel giddy. Cover half the distance... eventually you're advancing by millimeters and worse.

Hmm, the first paradox that came to mind was in your signature. I read it somewhere, but where is unknown to me.

9/10

If you play this game your brain will automatically cheat:

Look 2 lines down.
CHEATER!
Look 1 line down.
Look 3 lines up.
CHEATER!

Hmm.

A man wakes up one morning and an old man is standing next to him. He gives the younger man insructions on how to build a time machine, and is never heard of again. The young man builds he time machine. when he grows old, he decides to use the ime machine to go back in time and give the instuction manual to his younger self. He does.

Now the question remains: Where does the information in the instuction manual come from?

You can't see me   (highlight)

Proof that 0.99999...=1

Set x to 0.999...
multipling both sides by 10 we obtain
10x=9.99...
Subtracting x from both sides yeilds
9x=9
Divide both sides by nine and we get
x=1
Imput 0.999... for x and find that....
0.999....=1!!!
