Joe Simpson has made his daughters, Jessica and Ashlee Simpson, two of today's hottest pop superstars. But to do that, he had to dress Jessica in skimpy clothes and turn her marriage into a reality television show. The irony to some people is that he is a Baptist minister. Did he betray the values that he preached? And are his daughters paying a price for living in the spotlight? Joe Simpson, joined by Jessica and Ashlee, talks with "20/20" anchor Elizabeth Vargas about the decisions he has had to face to achieve the incredible success of his family business. The report airs on "20/20," FRIDAY, OCTOBER 29 (10:00 - 11:00 p.m., ET) on the ABC Television Network.

And: Is "gaydar" -- the word that denotes the ability to tell if someone is gay -- nonsense? Or do people really possess the ability to pick out someone who is gay based on the way they walk, talk, dress, or even just from intuition? In light of New Jersey's governors recent stunning announcement that he is gay, despite being married with children, "20/20" wanted to know if "gaydar" really exists, and found 10 men - five straight and five gay - to subject themselves to dozens of people's "gaydar." The testers mingled with our subjects for about an hour and then graded them. It was not a scientific test, but Northwestern University psychology professor Michael Baily, who has done scientific tests on "gaydar," said the test was valid. Did the testers guess correctly, and what clues did the people with the best "gaydar" look for? John Stossel reports.

Plus: Bob Brown introduces viewers to Brad Bird, the man behind the anticipated new 3-D, computer-animated film, "The Incredibles," made by Pixar Studios and released by The Walt Disney Corporation. The genius of Bird, who helped bring "The Simpsons" to television, is living his lifelong dream of being an animator. He talks to Brown about being the first outsider to direct a film at Pixar, and the first to bring an all-human cast to a Pixar film.

Also: Since the Bush administration says it will only fund a limited amount of embryonic stem cell research, some rich and powerful people in California have come up with a plan - to have California taxpayers pay for it. John Stossel says, "Give Me a Break."

"20/20" is anchored by Elizabeth Vargas and John Stossel. David Sloan is executive producer.
