The Alternative Lord of the Rings site presents a number of short snippets done in the styles of other famous authors. I enjoyed The Lord of the Rings, by A.A. Milne (really by Bill Taylor):
‘What we’re going to do,’ said Frodo, ‘is we’re going to go on an expotition.’‘Ooh’ said Pippin, ‘what will we discover?’
‘We’re not going to *discover* anything, Pippin, we’re going to undiscover uncle Bilbo’s old ring.’
‘CAN you undiscover things?’ asked Sam. ‘Discovering doesn’t seem to be a thing you can UN-, if you know what I mean.’
‘Sam’, said Frodo, sharpening his pencil, ‘You haven’t any brain.’
Sam shuffled off trying to look like he hadn’t said anything, and that it was one of Frodo’s many friends and relations. Frodo continued, ‘Anything that can be discovered, can be undiscovered, it stands to reason.’
‘My grandfather Brandybuck undiscovered his spectacles once,’ said Merry.
‘There you go then, that proves it then,’ said Frodo. ‘Of course, we shall have to beware of Trolls and Orcs and Things, that will try to stop us.’
‘Ooh’, said Pippin, shivering slightly, but only because it was cold, he told himself. ‘Do you mean they’ll chase us with swords and Other Deadly Weapons? Actually, I’ve just remembered something important I have to do, that can only be done on… what day is it tomorrow Merry?’
‘Pippin,’ said Frodo, sucking his new sharp pencil, ‘You haven’t any pluck!’
‘It’s hard to be brave,’ said Pippin looking crestfallen, ‘When you’re a very small hobbit.’
