‘Saturday Night’ doubles up

Tonight’s oddity

“Saturday Night Live,” 9 p.m. and 11:29 p.m., NBC. “Saturday Night Live” has thrived lately, with political sketches fueling high ratings. Now NBC doubles up, with the specifics unclear.

First, it reruns an episode hosted by Anne Hathaway, with music by The Killers; at various times, NBC has scheduled this for 9 p.m. or (following an “Office” rerun) 9:30 p.m. The political parts of the episode are clever; others are OK.

Then Jon Hamm (“Mad Men”) hosts a new episode, with music by Coldplay.

Other choices include

Baseball, 5 p.m. ET, Fox. Now the action is in Philadelphia. The Phillies host the Tampa Bay Rays in the third game of the best-of-seven series.

Football, 5 p.m. ET, ABC. Ohio State hosts Penn State in a battle of Big Ten powers.

“NCIS,” 8 p.m., CBS. Gibbs is working with Lt. Mann on a murder case. Complicating things: One of Gibbs’ ex-wives is a witness.

“Without a Trace,” 9 p.m., CBS. A man and his teen daughter disappear. This may involve his job, cleaning crime scenes.

Sunday’s muse-see

“Mad Men” season-finale, 10 p.m., AMC. This Emmy-winner wraps up its second season amid change.

Don has spent two episodes in California, ignoring his Manhattan ad agency. He wants to leave his wife (who threw him out after an affair) and marry a young woman he just met.

Meanwhile, there’s more change at work. Peggy has her own office now; the partners (minus the missing Don) have made an offer to sell.

Other Sunday choices include:

Baseball, 5 p.m., Fox. The fourth World Series game has Tampa Bay at Philadelphia.

“Cities of the Underworld,” 9 p.m., History Channel. England, it seems, is full of underground tunnels where evil things may or may not have happened. Here’s a moderately interesting tour.

“My Fair Wedding” debut, 10 p.m., WE. The bride has been planning her wedding for months. Now event-planner David Tutera arrives, shudders at the colors (green and purple) and starts over. It’s an OK hour, with likable people.
