An argument between a Pennsylvania couple over which American Idol finalist deserved to win the contest escalated quickly, resulting in a knife fight that left the pair bloodied and behind bars.

48-year-old Karen Elaine Harrelson and 57-year-old Gregory Stambaugh were hanging out in the basement of Stambaugh's West Manchester Township home last week, watching the American Idol season finale and drinking beers.

An argument ensued over which contestant deserved to take home the title — Candice Glover or Kree Harrison — and the verbal altercation soon turned violent.

According to Stambaugh, it was Harrelson who produced the first knife, stabbing him in the left forearm. He claims she was accidentally wounded during a subsequent struggle for the weapon.

Harrelson tells a different story.

In her statement to police, Harrelson said she was intending to use the knife to cut a piece of cake when Stambaugh suddenly approached her with a second knife and cut her wrist. She claims she had no choice but to stab Stambaugh in self-defense.

Ultimately, both Harrelson and Stambaugh were arrested and booked on charges of both aggravated and simple assault.

Though they were found by police on their porch with their clothes covered in blood, neither had sustained a serious injury.

For the record, Candice Glover beat Kree Harrison.
