Ninja Warrior

My family has found a new favorite show: Ninja Warrior on G4. The show starts with 100 people and puts them through a Ninja skills course, eliminating 90-95 of them in the first stage. The stages are courses that have back to back feats of strength and agility that require ridiculous strength and ninja skills - things like climbing across a 30 foot ceiling, holding onto globes suspended from the ceiling. The fourth stage (which we've never seen anyone get to) consists of a 300 foot tower that they have to scale in 30 seconds. The show comes from Japan and is all subtitled, but Ninja Skills know no borders.
