The host of a game show, offers the guest a choice of three doors. Behind one is a expensive car, but behind the other two are goats.
After you have chosen one door, he reveals one of the other two doors behind which is a goat (he wouldn't reveal a car).

Now he gives you the chance to switch to the other unrevealed door or stay at your initial choice. You will then get what is behind that door.

You cannot hear the goats from behind the doors, or in any way know which door has the prize.

Should you stay, or switch, or doesn't it matter?

It can't be seen, can't be felt, can't be heard, and can't be smelt.

It comes first and follows after, Ends life, and kills laughter.

Speaking of rivers, a man calls his dog from the opposite side of the river. The dog crosses the river without getting wet, and without using a bridge or boat. How?

What can run but never walks, has a mouth but never talks, has a head but never weeps, has a bed but never sleeps?

I never stop running even when I standstill. If I am formed by joining two identical bodies together, can you guess who I am?

You need to pick one entry from pot A and one from pot B to have a perfect match. Can you do it?

I travel all around the world but always stay in the corner. What am I?
