So I've been told

With wide screens it can be deceiving so it is best to to look at the actual dimensions or you may find your wide screen monitor does not have the same vertical dimension as an apparently smaller 4:3.

And every one said, 'If we only live,
We too will go to sea in a Sieve,---
To the hills of the Chankly Bore!'
Far and few, far and few, Are the lands where the Jumblies live;
Their heads are green, and their hands are blue, And they went to sea in a Sieve.
