Imaginary cow (a true experience)

This story is absolutely strange... however is not nothing at all

Long long time ago at India...
A father had 4 cows...
And when the father dies, he took one of the cow also (old school fairy tales...)
Ok la, one cow died. So now left 3 cows
But in the will which the father made before he died:
One quarter of the herd for each son

So now is it impossible to divide the cow evenly...
And Don't even thinking of cutting the cow because
Cow is a sacred animal in India...

The 3 sons could not think of a solution...
They discuss for whole day long... but still they couldn't find a fair solution
...
...
...
Still thinking...
Haiya no need to think so much
Then appear a very very handsome prince (cehhh...)
The handsomeness had nothing to do with the story line anyway
So this prince solve it easily.. while the 3 sons break their head whole day
And meet no solution...

The solution:
The prince lend one of his cow to the 3 sons.
So now there is 4 cows again
And so the son each get 1 cow each
the extra cow returned to the prince

See.. the prince did not lost any of his cow... (Damn smart)

Still wondering how it can happen? The cow is an imaginary cow...
