TONIGHT'S MUST-SEE

"Ice Age" (2002), 7 p.m., Fox. Yes, there really are family-friendly shows on the networks, especially this month. This animated film has a good-hearted mammoth (Ray Romano) trying to help a human baby. There are funny moments, especially with John Leguizamo as Sid the sloth.

OF NOTE

Ugly Betty," 7 p.m., ABC. This family-friendly (sometimes) show starts a night of reruns on all the big networks. Freddy Rodriguez of "Six Feet Under" plays a sandwich vendor who draws Betty's attention.

"30 Rock," 7:30 p.m., NBC. Last week, NBC yanked this show at the extremely last minute, so we'll have to see what happens tonight. The network says it has the episode in which Jack and his nemesis (Will Arnett) are expecting the GE chief (Rip Torn) to step down.
