When Indian Potatos are used to make French Fries, they change their citizenship from Indian to French.
Couch potato or Sweet potato? Whatever, When it becomes a 'french fry'
WHEN THEY ARE MADE FRENCH FRIES; THEY CHANGE THEIR NATIONALITY FROM INDIA TO FRENCH
It's not a baby though you hold in the arms close to your bosom. It's not an Indian man though it has long beard. It's not a monkey though its tail is bent. It's not a bird though it has beautiful voice. What am I?
