Bania's blood.

A rich man needed blood for his heart surgery.

He got it from a poor Bania.

The rich man gave him 5 million dollars. Once again the rich man needed blood for surgery.

Bania was more than happy to donated blood again. This time, the rich just gave him a Cadburyes Chocolate. Bania asked the reason.

The rich man now replied: “Now I also have Bania’s blood in my body.”
