Guess I better come up with a good one so that this second thread will seem justified... hmmm...

Guess what book I'm re-reading...

Merrydol-Derrydol
Tom Bombadillo was
Left out of Lord of Rings
Some say, "That's wrong!"
Jackson had found it was
Ultra-bewildering
Couldn't fit Tom in film
Four hours long.

Derrydol-Merrydol
Tolkien's Lord of the Rings
made into movie, fans
are not amused.
Where was Tom Bombadil?
Incomprehensibly
Left out of film version
Fans feel abused.
