A feeble-looking Michael Jackson (search ) ambled out of court in pajama bottoms Thursday after facing the boy who has accused him of child molestation for a second day and almost landing in jail for being late to court.

The pop star, wearing a coat over a T-shirt, walked gingerly into court after being treated at a hospital for what was described as a serious back problem. Jackson arrived after Judge Rodney S. Melville threatened to arrest him and revoke his $3 million bail; the judge later vacated the warrant.

Jurors got only a hint of the strange courtroom drama.

Melville was said to be furious and fed up with Jackson, and swore that such antics wouldn't happen again, sources told FOX News.

Attorneys met with the judge in chambers before court resumed and Melville told the jury that he had ordered Jackson to court, but advised the panel not to hold that as an indication of guilt or innocence.

"Mr. Jackson had a medical problem and it was necessary for me to order his appearance," Melville told jurors.

Jackson, 46, watched as his accuser described extensive liquor-laced visits with Jackson at Neverland, and of looking at sex magazines with the pop star and of being molested as he lay in Jackson's bed.

Under questioning by District Attorney Tom Sneddon (search), the boy said he remembered two sexual encounters.

In testimony that was hushed and sometimes mumbled, the young cancer survivor said Jackson molested him the first time in his bedroom under the covers after they returned from drinking in Neverland's arcade. It began with talk about masturbation, he claimed.

"He said if men don't masturbate they can get to a level where they might rape a girl or they can be kind of unstable," the boy said of Jackson.

The witness said he told Jackson he did not masturbate and Jackson said that if he didn't know how "he would do it for me."

He said Jackson masturbated him while they were under the bedcovers and he was wearing Jackson's pajamas.

The boy said the second molestation occurred "about a day after" and in that instance he resisted an attempt by Jackson to place the boy's hand on Jackson's genitals.

The boy claimed he ejaculated in both incidents and felt embarrassed but that Jackson tried to "comfort me."

In opening statements the defense noted that no DNA from the boy was found anywhere in Jackson's bedroom.

The accuser's testimony differed from his brother's earlier testimony and it was unclear if they were talking about the same incidents. The brother said he saw Jackson and the boy in their underwear and that the boy was asleep. The brother also said the boy was on top of the bedcovers.

On cross-examination, defense attorney Thomas Mesereau Jr. (search) alleged the accuser was making up the story. Jackson's attorneys have said the molestation claims are an attempt by the accuser's family to get money.

"Only after you met with Larry Feldman you started talking about inappropriate touching," said Mesereau, referring to a lawyer who handled another boy's allegations against Jackson in 1993 that ended with a civil settlement.

"I never told Larry Feldman," the boy said.

He acknowledged that he and his family went back to Neverland several times after meeting with attorneys.

Mesereau also attacked the boy's testimony that he did not feel that Jackson had done much for him when he had cancer.

"I didn't see him much," the boy said. "He was my best friend in the world and my best friend was trying to avoid me when I had cancer."

Mesereau, however, said Jackson called the boy three times a week for conversations of two to three hours, gave him gifts, invited him and his family to stay at Neverland for weeks at a time, had them stay at a Florida resort and had them chauffeured in limousines and a Rolls-Royce.

"Did your family go back and forth and stay at Neverland for free?" Mesereau asked.

"Everybody stays at Neverland for free," the boy answered defensively.

He was asked whether he knew that Jackson conducted a blood drive for him at Neverland.

"I heard something about a blood drive but I don't remember," he said.

"Can you look this jury in the eye and say that Michael did nothing for you when you had cancer?" Mesereau asked angrily.

"I didn't say he did nothing," the boy said. He said he felt other celebrities he had gotten to know did more for him, although he acknowledged that none had invited his family to live with them.

The boy suggested there was an instance when he was told Jackson was not at home but he bumped into him at the estate.

"My heart broke right there," he said.

The session ended with Mesereau questioning the boy about a lawsuit that his mother brought against J.C. Penney stores, claiming that the family had been abused by security guards.

He noted that in a deposition in that suit the boy said he was told what to say by lawyers, but the boy denied that Thursday.

Mesereau's cross-examination of the boy will resume Monday; the court planned to handle pending motions Friday.

Attorney Brian Oxman said Jackson will return to court Monday after recovering from an injury he suffered Thursday morning.

"He tripped this morning and fell in the early morning hours as he was getting dressed. His back is in terrible pain. He was in terrible discomfort throughout the proceedings."

As he left court, Jackson was asked if he was in pain and he nodded.
