Does Anybody Know Any Good Paradoxes or Riddles?

[acs267]

I just wanted to know if anybody had any extremely difficult paradoxes or riddles. Surprisingly, I love to work my brain to the point that it hurts sometimes, if I can't find the answer to a paradox or riddle. I'll start by sharing my favorite one. It's not necessarily hard, but it's just there:


One evening a boy is on his way home from school. As he is walking he comes to a fork in the road and cannot remember which path he took, but he knows from his travels that one path will lead him to a safe bridge, and the other will lead him to a broken bridge. He sees two twins at the fork. One of the twins always lies, and the other twin always tells the truth, and you can only ask each twin one question, and it has to be the same question. What question should you ask to find out which path is safe?

The answer is simple:

The answer is "What path would the other brother say is safe?"

The twin that always tells the truth would say "My brother would say take the left path" (assuming the right path is safe) because the brother would lie to you.

The twin that always lies would say "My brother would say take the left path" but that is a lie because the brother would not say that.

Tell us ! How long you can keep us with this in our heads ...

What comes into your house every day and twice on a Sunday?

Is it the sun? It doesn't exactly walk into your house, but if you have windows... plus, on a Sunday it would come in as usual and it would be a Sun + day.

Alright my turn then: what is it that enters the water and doesn't get wet?

I'm sure there are many answers for that one, so don't take it too far...  

In terms of paradoxes, have you guys heard of the "Ship of Theseus" (http://en.wikipedia.org/wiki/Ship_of_Theseus)?

[Hazir]

A murderer is condemned to death. He has to choose between three rooms.
The first is full of raging fires, the second is full of assassins with loaded guns, and the third is full of lions that haven't eaten in 3 years.
Which room is safest for him?

Here's a good paradox from the forum idiot. 

Non existence does not exist.

I already know the answer to that one, so I won't spoil it.  

But here are a few sites I had bookmarked with a lot of very good riddles, or to be more precise, lateral thinking puzzles:

Obviously the dead lions.

Haha, correct.

And this one?

You may always chase me but you are always about 3 miles away.

What am I?

Oh, yes. The Ship of Theseus? I think it would be different, of course.

Well, there's many things that you can never get close to. But I'm guessing this deals with the sky or something astronomical?

Well, it is close enough I suppose. It is the horizon.

[u9y42]

Well, it isn't exactly clear to everyone that it would be different, though I myself agree, up to a point. But at what point do you consider it would be a different ship? After the first patch of the ship, or when it was composed of completely different materials? Or at some other point?

Also, if a second ship was built using only the materials of the first ship, would this be the original ship?

[Hazir]

I got a good one:

There is a 100 pound watermelon laying out in the sun. 99 percent of the watermelon's weight is water. After laying out for a few hours 98 percent of the watermelon's weight is water.

How much water evaporated?

I don't think anything can be the same of anything, even if it's made of the same materials. It's just not the same anything, because something has to be different about it. From it's owner to anything else. If it was built out of the same materials of the first ship, then it can't necessarily be the same ship. Based on it's width, design, height, weight, worth, and things like that. I don't think it's solely possible for the same anything to be the same material of anything.
