Santa Singh, his wife and his son were returning to Punjab by train.
Santa Singh was occupying the lower berth, his wife the middle berth and his son the top most berth in the train compartment. The train stopped at one of the stations on the way back and the son asked Santa Singh to bring him a Cadbury's chocolate.

When Santa and his son returned they found that a South Indian who couldn't understand Hindi had occupied his son`s berth. Upset and angry, Santa Singh called the Ticket checker asked him to help.

The Ticket checker said that he could not understand Hindi or Punjabi so it would be nice if Santa Singh explained the whole situation to him in English. Santa Singh explained, 'That man sleeping on top of my wife is not giving birth to my child.'
