Book Seven Titles the Fandom Would Have Preferred
Harry Potter and the Hallows that Have Nothing to Do With Death
Harry Potter and the Fluffy Pink Hallows
Harry Potter and the Grammatically Correct Title
Harry Potter and the Title That Have Nothing to Do With the Books, So Don't Fret
Harry Potter and the Book in Which He Doesn't Die
Harry Potter and the Fandom that Lived On Despite the End of Canon
Harry Potter and the Assurance That No One is Getting Jossed
Harry Potter and the Debate Over Whether Titles are Spoilers
Harry Potter and the Seriously People Life Will Go On Even If Harry Doesn't
And my personal favorite, Harry Potter and the Final Book of the Series in Which Nothing Bad Happens To Your Favorite Characters, No Stupid Bint Comes in Between Your Ship, Harry Definitely Doesn't Die, and There Remains So Much Room for Fic and Fandom Discussion for Years To Come.
