Upon discovering another man in bed with his girlfriend, a furious Chicago man got medieval on his rival, allegedly setting his genitals on fire with a Bic lighter. 

It was a normal Monday afternoon until the man showed up at his girlfriend's home and found her engaged in extremely reckless sex with an unidentified 30-year-old man. After beating the man until he lost consciousness, the assailant decided to teach him a lesson by lighting his balls on fire, allegedly uttering the horrendous movie villain quote: "This will be a lesson to you, I lit your (genitals) on fire." Who does or says that?

Once the victim regained consciousness, he ran to a laundromat, where police found him applying Vasoline to his burns. He was taken to Holy Cross Hospital, then transferred to the University of Chicago's burn unit. 

Somehow, no one was arrested.
