He couldn't be a builder 'cos he didn't like the labour and
he couldn't work abroad 'cos he really liked his neighbour
He couldn't be a milkman 'cos he liked to stay in bed a bit
He couldn't be a scientist 'cos he didn't have the head for it

He couldn't be a painter, couldn't keep within the lines
Couldn't be a policeman, he gave everybody fines
He would have been a space cadet, but he had no starship
He couldn't be a chef, to him what was a parsnip

He was the wizard's apprentice
And these were his motives:

Just think if you could change the sun to gold
If you could fight with knights of old
If you could stop hair turning grey
If you could turn night to day
