The spaceship was blasted off from the launch pad without a hitch and when in orbit the occupants were told to open their sealed orders.

The occupants happened to be a monkey and Paddy.

The monkey opened the envelope that was about a foot thick,inside were all the million and one things that a space rocket ship driver has to do.

Check this check that,do this experiment and so on, when he got to the bottom of the pile there was a small envelope addressed to Paddy.

He opened it and saw on the even smaller piece of paper these three words.

Feed the monkey.
