I was just channel flipping tonight and found this totally cool show called Ninja Warrior on G4.

It's this really cool Japanese obstacle course competition where they start with 100 challengers and each person tries to make it through stages 1-4. It's in japanese with english subtitles which is cool because there are crazy enthusiastic Japanese commentators. Apparently the show has been around since 1997 with 2 competitions each year and since then only 2 people have ever completed all 4 stages. Its my new favorite show!

It starts out kind of silly on the first stage and then gets very serious as the show progresses.
Taken from DI forums.

There has even been some Olympic champions like gymnasts like Paul Hamm and his brother Morgan. I guess Paul couldnt get pass the second stage.

Its cool you should give it a shot
