CBS swept the night, beginning with the 6.1/12 for "Big Brother 5" in the 8 p.m. hour. NBC got a 4.8/9 out of two episodes of "Will & Grace" to beat UPN’s "WWE Smackdown!" for second. Fourth went to the first part of the finale of ABC’s "Stephen King’s Kingdom Hospital," which did a 2.9/6. FOX’s repeat of "North Shore" was fifth with a 2.3/4, with The WB in last with "Pepsi Smash."

The night’s highest rated program was CBS’ "CSI: Crime Scene Investigation," which did a 9.5/17 for the 9 p.m. hour. NBC stayed second with its "Will & Grace" reruns, but "Smackdown!" improved to a 3.6/6 for third. "Kingdom Hospital" fizzled to a 2.2/4 in its second hour, still better than FOX’s "Tru Calling." The WB trailed with the 1.6/3 for "Jamie Kennedy Experiment."
