Believe it or not, I haven’t been on a skateboard since Lyndon Johnson was president. So I don’t know anything about the intense and competitive subculture of skateboarding. That’s why I am sure to tune into “The Skateboard Show,” (7:30 p.m., WB). Led by former MTV shock-value comic Tom Green, “Skateboard” will provide a half-hour primer on the moves, the culture, the music and slang-ridden patois of serious skaters, including Tony Hawk, Chad Muskas and others. Who are they? Don’t ask me. I wouldn’t know a half-pipe from an aerial, but that’s why I’ll be watching. “Skateboard” includes both taped field segments and live studio stunts. There will also be live music from Saves the Day, a band I’ve never heard of. I can’t wait.

The grim news from the Middle East makes it hard to remember a time when the Israelis and the Palestinians appeared to be on the verge of a historic reconciliation. The two-hour documentary “Shattered Dreams of Peace,” on “Frontline,” (8 p.m., PBS, check local listings), examines the long and frustrating process of negotiations between both sides, from the promising 1993 Oslo Peace Accords to the failed Camp David summit in 2000, when Yasser Arafat rejected an offer that Former Secretary of State Madeleine Albright calls “one of the best deals he can ever have.” Soon after those talks broke down, Palestinians began a second uprising that continues to this day.

Having chronicled the lives of teen wrestlers, methamphetamine users and plastic surgery abusers, the documentary series “True Life,” (9 p.m., MTV) looks at three young people as they reveal their homosexuality to parents, family and friends. While the pain and anguish of Joel, 19, and Dora, 17, seems very real, their heart-to-hearts with their fathers were either captured by the world’s most discreet cameras, or were, in fact, re-enactments of the most intimate kind.
