We've seen some pretty crazy stuff on TLC's "My Strange Addiction" ... but this one is just insane!
Meet 20-year-old Shannon, who on Sunday night's episode of the show is seen drinking gasoline straight out of a gas can.
"It tastes like sweet and sour, or like a tangy sauce," she says in a promo clip from the episode. "It tingles at first, it burns the back of my throat. Even though it hurts me, it makes me feel good."
Shannon drinks 12 teaspoons a day ... and downed 5 gallons last year alone!
The clip also introduces viewers to 24-year-old Lacey, who is addicted to smelling a dirty old doll head.
