God is sitting in Heaven when a scientist says to Him  

 'Lord, we don't need you anymore. Science has  finally figured out a way to create        
         
life out of nothing.  In other  words, we can now do what you did in the 'beginning'.'            
               
'Oh, is that  so? Tell me...' replies God.            
      
'Well', says the scientist, 'we can  take dirt and form it into the likeness of you and breathe life into  it, thus creating man.'            
      

 'Well,  that's interesting. Show Me.  '            
      
        
So the scientist bends down to the earth and starts to mold the soil.            
      
'Oh  no, no, no...' interrupts   God,            
      
 (I love  this)            
      

'Get  your own  dirt.'
