"Just Joking" Justification/Quotes

Everything About Fiction You Never Wanted to Know.

"Like a madman shooting firebrands or deadly arrows is a man who deceives his neighbour and says, 'I was only joking!'"
The Bible (New International Version), Proverbs 26:18-19
"Cruelty is shameful--unless the cruel man can represent it as a practical joke. A thousand bawdy, or even blasphemous, jokes do not help towards a man’s damnation so much as his discovery that almost anything he wants to do can be done, not only without the disapproval but with the admiration of his fellows, if only it can get itself treated as a joke."
The Screwtape Letters, chapter 11
