Oprah's Master Class and Oprah's Lifeclass are probably the best shows on OWN. (They are almost identically named and their content is virtually the same but they are not the same.) Why? Because while Master Class and Lifeclass air episodes with visionaries like Maya Angelou sharing their thoughts about Living Your Best Life, they also air episodes with people like...Billy Bob Thornton.

Thornton's episode is set for this Sunday night and he's already poised and ready with some wisdom, if these promo clips are to be believed.

"When your mom's psychic, it's not easy to sneak in the house drunk at night, I'll tell you that," says Thornton. But the best quote is: "I've only had a couple of times in my life when I was carefree. And then he died. And I've never trusted happiness since." [Thornton smiles, somewhat scarily.] TELL ME MORE.
