I can see Rowling sitting at her computer, thinking intently, and then exclaiming:
"FUCK IT! I'm already rich. I already have my own fucking castle. Now I can write that Harry yaoi fantasy I've been burning to tell, since I don't care what the editors and publishers and critics think anymore! YEAH! I'll call it 'Harry Potter and the Seven Throbbing Cocks'! OH, YEAH!!"
