Lancashire man, Londoner, Brummie and Yorkshire man are all in a private jet. Soon the aeroplane runs into difficulties and the four men all draw up an agreement that whoever died, each of the survivors would put £200 each into the dead man's coffin to help him on the way to the next world.
Sure enough, the Londoner dies and the Lancashire man, Brummie and Yorkshireman all agree to putting £200 into the Londoner's coffin. The Brummie puts in his £200 in £20 notes, the Lancashire man puts his £200 in £10 notes.
They leave the Yorkshireman to put his money into the coffin - our man from Barnsley writes out a cheque for £600 and takes £400 change.
