Biography (8 p.m., A&E) continues "Charlie's Angels" week with a profile of Jaclyn Smith (aka "the refined one"). 48 Hours (8 p.m., CBS) reports on a 1999 warehouse fire in Massachusetts that killed six firefighters. On Gilmore Girls (8 p.m., WB), Lorelai is smitten with Rory's teacher, Rory encounters the boy she left behind and Michel is annoyed by a plague of French tourists. Jack spices up his tired cabaret act with some nasty new material about Will on Will & Grace (9 p.m., NBC). David Cross returns as Elliott's con artist brother on Just Shoot Me (9:30 p.m., NBC). On ER (10 p.m., NBC), an elderly patient suffers from violent delusions that he's back in the Korean War. The ads are promising another one of those episodes where "everything changes."
Lifting its self-imposed "Who Wants to Marry a Multi-Millionaire?" moratorium, Fox presents Surprise Wedding (8 p.m., Fox), in which five women ambush their boyfriends with marriage proposals. Well, if it's good enough for "Jenny Jones" and "Maury," it's good enough for Fox.
