Here's a good one one:
"The greatest writer of the Renaissance was Shakespeare. He was born in 1564, supposedly on his birthday. He never made much money and is famous only because of his plays.
"He wrote tragedies, comedies and hysterectomies - all in Islamic pentameter."
But my favourite:
...wrote that Caesar had been murdered by the Ides of March and that his
dying words were "same to you, Brutus".
