“If the facts do not fit the theory then change the facts!” – Einstein

There’s a great joke about Einstein of when he was a teacher, referring to that quote.
His “secretary” was horrified when she was asked to print out last year’s physics test to this year’s exam. When she confronted him, saying “You can’t give a test with the same questions as last year!”, Einstein looked at her and smiled. “Not to worry”, he said, “I’ve changed the answers!”
