Boos is right

An employee goes to his boss to discuss his appraisal. Boss starts asking questions:

Boss - There are 50 bricks on an airplane. If u drop 1 outside. How many are left?

Employee - That's easy. There are 49 left.

Boss - How would you put an elephant into a fridge?

Employee - Open the fridge. Put the elephant in. Then close the fridge.

Boss - How would you put a deer into the fridge?

Employee - Open the fridge. Take the elephant out. Put the deer in. Then close the fridge.

Boss - It's the lion's birthday. All animals are at the party except one. Who is missing & why?

Employee - Deer is missing because it is in the fridge.

Boss - An old woman wants to cross a swamp
filled with crocodiles. How will she do it?

Employee - She just has to cross from 1 side to the other because all the crocodiles are at the lion's birthday party.

Boss - Last question.
The old lady still died why crossing the swamp. How?

Employee - Err... I guess she drowned?

Boss - No! She was hit by the brick that fell from the airplane.
You may leave.

Moral: Jitna marzi prepare karlo. Agar boss ko tumhari leni hai to leke hi manega. kyuki har ek boss kamina hota hai..:) issued in interest of all the subordinates.:)
