Dr. Phil (search) pulled off his highest overnight rating ever last Thursday with a dramatic show about a 19-year-old sexual predator.

More than 7.6 million homes watched the second episode of a two-part show called "Is My Son a Sexual Predator?" Precise figures would not be available until tomorrow.

The show began last Wednesday when the boy's parents told Dr. Phil they suspected their teenage son had molested his younger sister.

The 19-year-old boy protested his innocence, agreed to take a polygraoph test on Thursday but failed the test.

At the end, the young man admited he has molested several women, inlcuding his sister.

The "Dr. Phil" show has been on the air since September 2002. The previous best show aired last February. It was about women who were trying to marry rich men.
