I've Believed as Many as Six Impossible Things Before Breakfast

'I can't believe that!' said Alice.
'Can't you?' the Queen said in a pitying tone. 'Try again: draw a long breath, and shut your eyes.'
Alice laughed. 'There's no use trying,' she said: 'One can't believe impossible things.'
'I daresay you haven't had much practice,' said the Queen. 'When I was your age, I always did it for half-an-hour a day. Why, sometimes, I've believed as many as six impossible things before breakfast.'
