Rabbit

The first person he met was Rabbit. ‘Hallo, Rabbit,’ he said, ‘is that you?’
‘Let’s pretend it isn’t,’ said Rabbit, ‘and see what happens.’

-A. A. Milne, Winnie the Pooh, chapter 8 ... in which Christopher Robin leads an ‘expotition’ to the North Pole
(quoted in "Who made God?" - Edgar Andrews, chapter 6)

That is quality humour, friends. Quality. And it can even make you think!
