What with Dancing With the Stars and So You Think You Can Dance, America is growing more dance-crazed as we speak - and what could be better than that? (Okay, an obsession with reading or learning about geography wouldn't hurt, but in an effort to avoid raising little couch tater tots, let us ponder the subject of physical activity.) Based on the popular video game Dance Dance Revolution, this American Idolish dance competition will have your twins rooting for their favorite ''crew'' (dance pairs who are eliminated each week) and learning some serious hip-hop moves (the Roller Coaster, the Charleston Brush, the Scoop, and the Glide, all broken down so even someone much older than 12 - we're looking at you, Mom! - can bust a move). Host Rick Adams could give Ryan Seacrest a run for his money, and judge Tricia Gomez (a former Laker Girl, just like Paula) offers valuable constructive criticism - take note, Simon!
