Santa Maria, Calif. ? Michael Jackson’s young accuser took the witness stand Wednesday, saying he once considered the pop star now charged with molesting him “the coolest guy in the world.”

The 15-year-old was not asked about the molestation allegations before court ended for the day, but he described viewing adult Internet sites with Jackson present and said the singer told him to “call me daddy” during the taping of a documentary.

With an expression that appeared to verge on a sneer, the young cancer survivor said yes when Dist. Atty. Tom Sneddon asked him whether he recognized the defendant.

The accuser followed to the stand his 14-year-old brother, who testified he saw Jackson grope his sibling in 2003.

The boy gave the same account his brother had of looking at sexually explicit Web sites on their second night at Neverland after their parents gave them permission to sleep in Jackson’s room. He said it was Jackson’s idea that they sleep in his room.

The boy said one of Jackson’s employees, Frank Tyson, began looking at sites on the Internet as the others watched.

The witness said they looked at women or teenage girls on about seven sites for a period of 15 to 30 minutes.

Jackson, 46, is accused of molesting the boy, giving him alcohol and conspiring to hold the boy’s family captive to get them to rebut a damaging TV documentary in which Jackson said he allowed children to sleep in his bedroom. Jackson’s defense contends the family has a history of filing false claims to get money.

Earlier Wednesday, the accuser’s younger brother, under cross-examination by defense lawyer Thomas Mesereau Jr., admitted discrepancies between his testimony and his other accounts of allegedly seeing Jackson molest his brother.

During questioning by the prosecution the boy told of twice looking through the doorway of Jackson’s bedroom and witnessing the molestation.

Mesereau confronted the witness with a previous statement to sheriff’s investigators in which he said that during the second incident he was in the room curled up on a small couch pretending to sleep.

When Mesereau asked if his account of the second molestation had changed, the boy interjected that there were actually three incidents, although that has never been alleged.

“I was nervous while I was doing the interview,” he told Mesereau.

“Because you were nervous you didn’t get the facts right?” the attorney asked.

“Yes,” the witness said.
