FILL IN CAPITAL

One great day in Bombay, a couple were on a honeymoon tour. They saw one sardarji in front of a hospital (Breach Candy) was trying to fill some form. So the couple enquired eagerly ""What are you doing ?. Sardarji replied that I had a baby and I am filling the birth certificate form. The couple as per schedule, took the Bombay to Delhi Flight for their next destination. On the next day, they find the same Sardarji, in front of Lal Qilla in Delhi filling the same form. So once again young couple curiously asked - ""What are you doing here ?"" Sardarji once again replied I had a baby and I am filling the birth certificate form. The couple said but sardarji yesterday you were in Bombay filling the same form, how come you-re in Delhi?
Sardarji coolly replied It is written here - ""FILL IN CAPITALS""
