Big Brother 2, which received a slight boost in its ratings when one of the contestants, Justin Sebik, was booted off the show after pulling a knife on another, saw its numbers sliced down again on Saturday. Still, the average 3.8 rating and 8 share -- miserable by the standards of regular-season primetime -- was good enough to win the hour for CBS and also help the network win the night. Meanwhile, contestant Autumn Daly, who was booted off the show last Thursday, has told the New York Daily News that contestants were never told that the knife incident was the reason for Sebik's leaving or that he had an arrest record including assault and robbery. "It scared me to death," Daly told the newspaper. "You're living in a confined situation, where if anybody lost control, you're stuck with them." She also said she thought the show should be renamed What Crazy and Stupid Things Would People Do for Money?
