NBC was second for the night with a 2.8/9 for its combination of repeats--back to back Will & Grace--and a new episode of Last Comic Standing.
ABC was third with a 2.2/7 for its mix of repeats--back to back Extreme Makeover--and a new Prime Time.
Fox was fourth with a 1.8/6 for a repeat of Adam Sandler theatrical Little Nicky, barely edging out UPN, which scored a 1.7/5 for WWE Smackdown (UPN beat out Fox for fourth in households). WB was in sixth with a 1.2/4 for Blue Collar TV (which actually beat out ABC's Makeover for third place for the 8-8:30 half-hour), Reba, and Studio 7.
