Charlie and the Chocolate Factory: Level 3

HE CANNOT THINK — HE ONLY SEES!
"All right!" you'll cry. "All right!" you'll say,
"But if we take the set away,
What shall we do to entertain
Our darling children! Please explain!"
We'll answer this by asking you,
"What used the darling ones to do?
How used they keep themselves contented
Before this monster was invented?"
Have you forgotten? Don't you know?
We'll say it very loud and slow:
THEY … USED TO … READ! They'd READ and READ,

AND READ and READ, and then proceed

TO READ some more. Great Scott! Gadzooks!
