A secret

Two sisters in twin towers stand,

One from sea and one from land,

One dark as night, one fair as day;

Tell me truly, who are they?

Turn us on our backs
And open up our stomachs
You will be the wisest of men
Though at start, a lummox.

What are we?

It can be said:
To be gold is to be good;
To be stone is to be nothing;
To be glass is to be fragile;
To be cold is to be cruel.
Unmetaphored, what am I?

With pointed fangs I sit and wait;

with piercing force I crunch out fate;

grabbing victims, proclaiming might;

physically joining them with a single bite.

What am I?

In The Hobbit there was one.
Harry Potter had more than three.
If you were to make one mad,
From its mouth, fire you would see.

What is it?

A house with two occupants, sometimes one, rarely three. Break the walls, eat the boarders, then throw away me. What am I?

how can you rearrage the letters in "new door" to make one word?

I have many feathers to help me fly.

I have a body and head, but I'm not alive.

It is your strength which determines how far I go.

You can hold me in your hand, but I'm never thrown.

What am I?

A Japanese ship was sailing in the Pacific Ocean. The Japanese captain of the ship put his diamond chain and Rolex watch on a shelf, went to get a shower and returned ten minutes later. Now listen carefully, as I will only tell it once: When he returned, both the chain and the watch were missing!! He called the crew of his ship together. There were four of them. A British guy was the cook of the ship. The captain asked him: "Where were you the last ten minutes?" And the cook answered "I was in the cold storage room to select the meat for lunch". A Sri Lankan was the house keeping guy. The captain repeated his question to him, and learnt that the Sri Lankan was at the top of the ship correcting the flag which had been put upside down. An Indian guy was the engineer maintaining the ship. Same question, and the Indian told that the he was in the generator room checking the generator. A French guy also served on the house keeping crew. Same question, and the French told that he was sleeping after the night shift. Within ten seconds the smart captain caught the thief. Who was the thief? How did the captain find him?
