I'm watching this show on G4TV called NINJA WARRIOR. It's fun to see. It reminds me of American Gladiators, but I like Ninja Warrior better. Basically, there's this obstical course for challengers to pass. It requires ninja-like agility and strength. It's awesome.
Looks like an awesome show .. I've never seen a full episode before, but I found a clip on YouTube where an Olympian was running the first course. Looks pretty hard
