Jackson also has been candid and jocular about his suffering from possibly a combination of personality disorders, such as obsessive compulsive disorder, depression and social anxiety. He says he lies in bed and hears songs or phrases repeat themselves over and over. Mostly these intrusive and repetitive thoughts are Warner Bros. themed. Also in early 2007, Bill was allowed to read an email from a listener that had seen Jackson shopping, who was noticeably irate and wrathful, due to being surrounded by too many people. Jackson is also a survivor of testicular cancer and often makes jokes about how he now only has one real testicle.
