Following up Joaquin Phoenix’s bizarre interview with David Letterman last month, Billy Bob Thornton sounded wacked out of his gourd yesterday (April 8) during a radio interview in Canada.

The “Monster’s Ball” actor and his band the Boxmasters did a promotional spot on CBC public radio during which the host, Jian Ghomeshi, had a hard time extracting intelligible answers.

When asked about the formation of the band, Thornton looked dazed and confused as he answered, “I don’t’ know what you’re talking about.”

Billy Bob also went on a strange tangent when questioned about his musical influences, opting instead to rant about a monster comic book magazine.

At the end of the interview, Thornton’s three bandmates grabbed their instruments to do a live performance while Billy Bob kept his seat, deciding not to play along.  His reason?  “I’m a drummer.  We don’t cart those around at 6 o’clock in the morning.”
