A slave who became a Jedi
But turned into a Sith Lord-i
He killed his wife and his master-i
And made the whole audience cry
Then his son and daughter came
And saved him from Emperor Lame
And the big, mean, evil Sith Lord-i
Turned back to a jolly good Jedi
But just right after that he died
And made the whole audience cry
