"The Jerry Springer Show" (1 p.m., WPWR-Channel 50): A 22-year-old college student named Lisa won an eight-month-long contest to "Be Jerry for a Day," and today is the day. She co-hosts and tries to follow in Springer’s footsteps.

"Rudolph the Red-Nosed Reindeer" (7 p.m., WBBM-Channel 2): The **** Christmas perennial returns to TV for an hour. This is the one where gold digger Yukon Cornelius says, "Observe the bumble’s one weakness. ... The bumble sinks!"

"Christmas in Rockefeller Center" (7 p.m., WMAQ-Channel 5): Oldies Rod Stewart, Sheryl Crow and Earth, Wind & Fire perform and chat for the holidays. Al Roker co-hosts.

"Great Performances: Cream Reunion Concert" (7:30 p.m., WTTW-Channel 11): The classic-rock band plays songs recorded over the course of four nights, revisiting "Sunshine of Your Love" et al. How long has Eric Clapton’s old band been split? Cream broke up in 1968, two years before PBS began broadcasting.

"Lost" (8 p.m., WLS-Channel 7): Kate’s crime is revealed some two months or so — that’s a season and a half to viewers — after the plane crashed on the island of unsolvable nonsense. ABC waited till the last night of November ratings to let viewers in on this little and inexplicably kept secret. Watch if you want, but "Veronica Mars" will certainly be better.

"Veronica Mars" (8 p.m., WPWR-Channel 50): Alyson Hannigan returns in a guest spot and appears in a funny scene with Charisma Carpenter, but it’s not funny just because those two used to be in "Buffy the Vampire Slayer"; Jason Dohring, as Logan, delivers the second-best line of the season when he introduces the women to each other. A **** show with lots of juicy stuff. An alternate ending is being posted at aol.com.
