"Galaxy Quest" (1999), 7 p.m., ABC. This delightful comedy imagines there was once a "Galaxy Quest" series, a lot like "Star Trek." Decades later, the egotistical star and other actors are reduced to doing conventions and store openings. Then along come real space aliens who mistake the reruns for historical documents.
"Friends," 7 p.m., NBC. Here's a solution to having a weak show on Thursdays: NBC simply expands its strong ones ("Friends," "Will & Grace," "Scrubs") to 40 minutes each, scuttling "Good Morning, Miami" for a week. This episode stuffs in three guest stars Freddie Prinze Jr. as Rachel's baby's nanny, Paul Rudd as Phoebe's current love and Hank Azaria as her past one returned from Russia. Meanwhile, Chandler fumes because Monica has a co-worker with a better sense of humor than his.
"SURVIVOR: THAILAND," 7 p.m., CBS. People consider new alliances and oust an eighth person.
"WITHOUT A TRACE," 9 p.m., CBS. The team's usual methods won't work when a tot disappears.
