There's a Space Shuttle mission to the moon with 2 monkeys and a woman 
on board.

The headquarters in the US  calls:
"Monkey #1, Monkey #1 report to coms for instructions."
He sits down and he is told to release the pressure in compartment 1, 
increase the temperature in engine 4 and to release oxygen to the 
reactors.  So the monkey does the pressure, temperature, and releases
the oxygen.

A few moments later headquarters  calls again:   "Monkey #2, Monkey #2
report to coms for  instructions."  He sits down and he is told to add
Carbon Dioxide to room  4, to stop the  fuel injection to engine 3, to 
add nitrogen to the fuel  compartment and to  analyse the solar 
radiation. So the monkey does the  carbon dioxide, the  fuel injection, 
the nitrogen and the analysis of  solar radiation.

A little later on, headquarters  calls again:   "Woman, woman please 
report to coms for  instructions."  She sits down and just as she is 
about to be told what to  do she says.....    "I know, I know!! Feed
the monkeys, and don't  touch a damn thing."
