Donkey : "Now I have worked for you more than 20 years".
Man : So tell me, What do you want me to do?
Donkey : OK, I want a partner, can you find me a partner?
Then he realized that he needs to do something to make happy this bud.
He searched everywhere in the town, But he could not find a female donkey anywhere in the city. Finally he went to a circus crew and requested a female donkey for rent. Unfortunately they couldn't satisfy him.
But they requested to bring female Zebra instead of female donkey. Finally he agreed to get lady Zebra for 5 pounds.
He is so happy and handover lady zebra to his donkey and went to sleep.
Following day he went to donkey and asked "How was your last night? Is it interesting?"
Donkey said : "It is useless and what a waste of time". I tried so many times,
