The final horcrux turns out to be Harry's scar, and the only way he can defeat Voldemort is to kill himself. This one actually sounds dangerously plausible, so let's try this one instead:
Harry turns out to be the love child of Lily Evans and Snape. Snape also had an affair with Narcissa Malfoy, so Draco Malfoy is Harry's half brother. Voldemort cast a spell on a certain dentist, so Hermione is actually his daughter. Meanwhile Dolores Umbridge was the end product of Aberforth Dumbledore's inappropriate spells on a goat. Maybe not true, but wouldn't it be more entertaining if it was?
