Off the Wall uses duct tape for everything, too.

THE WONDERS OF DUCT TAPE! Can you build a boat with it? Shoes? Water containers? We'll find out when "MythBusters" (Sunday at 9 p.m., Discovery) moves to its new night and time: Adam and Jamie are "marooned" on "a desert island" -- really, a Hawaii beach -- supplied with nothing but duct tape. (Better make sure your kids can't get to yours after watching this.) It's followed by the guys' new competition spinoff "Unchained Reaction" (Sunday at 10 p.m., Discovery). But first, check out Sunday's 9 a.m.-6 p.m. marathon. Or discovery.com/mythbusters.

DID YOU KNOW THERESA IS BACK? Well, then, maybe you're not psychic like "Long Island Medium" (Sunday at 9 and 9:30 p.m., TLC). Hicksville's Theresa Caputo also does her thing in 4-9 p.m. encore episodes leading into the second-season premiere. More at tlc.com/longislandmedium.

UNSCRIPTED PREMIERES Because cable never has enough "reality" series involving tattoos, here comes "Best Ink" (Tuesday at 10 p.m., Oxygen), with 10 artists competing for a Tattoo magazine spread. Of course, there isn't enough obsessive-compulsive behavior on TV, either, so here comes "My Mom Is Obsessed" (Thursday at 10 p.m., Discovery Fit & Health). Singing sisters Erica and Tina Campbell take viewers behind the scenes of their gospel duo "Mary Mary" (Thursday at 10 p.m., WE; thereafter, Thursday 9 p.m.) to their everyday lives as wives and mothers. The classic prankfest "Punk'd" (Thursday at 10 p.m., MTV) resurfaces with weekly guest hosts (Justin Bieber, Miley Cyrus, Nick Cannon, et al) and celebrity victims -- oops, subjects -- including Zac Efron, Darrelle Revis, Khloe Kardashian Odom, Taylor Swift and many more. It's followed by the "Jersey Shore" spinoff "The Pauly D Project" (Thursday at 10:30 p.m., MTV), as Pauly shoots for DJ fame. "Punk'd" preview at on.mtv.com/ ywfQ0j.

SECOND TO THE POLE It's another 100-year anniversary, this time since famed British explorer Robert Falcon Scott died during his Terra Nova expedition to Antarctica's South Pole, returning from the discovery that Roald Amundsen had beaten him to glory. John Mills stars in the 1948 adventure "Scott of the Antarctic" (Thursday at 8 p.m., Turner Classic Movies), followed by other pole pictures -- 1969's "Ice Station Zebra" (10 p.m.), 1931's "Dirigible" (12:45 a.m.), 1931's "The Viking" (2:30 a.m.), the 1930 documentary "With Byrd at the South Pole" (3:45 a.m.), and 1951's original thriller "The Thing From Another World" (Friday morning at 5:15 a.m., all on TCM). Learn about the films at tcm.com/this-month.

YIDDISH THEATER SALUTE Michael Tilson Thomas isn't just a renowned conductor. He's also the writer/host of "The Thomashefskys" (Thursday at 8:30 p.m., PBS/13), a new "Great Performances" portrait of his grandparents, Boris and Bessie Thomashefsky. They supported immigrant Yiddish theater -- by hosting shows and sponsoring young artists -- as it blended European klezmer sounds with new American rhythms. More at pbs.org/gperf/episodes.

BASEBALL TREASURE While New York teams build new and demolish old, Boston does it differently.
