Not exactly brotherly love.

A 13-year-old Tennessee boy told authorities in Florida that he stabbed his older brother because he’d rather spend time in the slammer than be stuck in the car for hours with his sibling.

The teen suspect, from Tennessee, was arrested Saturday for stabbing his 15-year-old brother three times in the arm with a pocket knife, local authorities said.

He was charged with aggravated battery with a deadly weapon.

Investigators at the Okaloosa County Sheriff’s Office said during questioning the youngster wasn’t remorseful for carrying out the attack, even admitting, “I’d rather be in jail than eight hours in the car with him.”

The 15-year-old was not seriously injured.

The teen added that his brother had been teasing him before the stabbing.
