Gavin Arvizo was fifteen years old when he testified, telling the court that after "Living with Michael Jackson" aired, Jackson had begun serving him and his younger brother wine, sometimes concealed in soda cans, showing them pornography and making sexual advances. He said that Jackson had masturbated him to ejaculation after they drank alcohol, and then told him that if men do not masturbate, they "might rape a girl." Challenged by Mesereau, who said that Gavin had told sheriffs that his grandmother had said this, Gavin said "I'm not exactly sure what my grandmother told me." Gavin admitted that he had told his school administrator that Jackson had not molested him.
