American Wusses.

One thing I have learned by watching The New American Gladiators (it was accident, I swear!) is that Americans are a bunch of pansies. Not a single contender -- or "gladiator" has anything on a Ninja Warrior.

I know it's harder than it looks, but the stuff on Ninja Warrior looks really hard. None of this running up a conveyor belt with the aid of a rope. In Japan, you must run against the conveyor belt using your own stamina and strength!

Of course, I also would have difficulty doing much of anything requiring physical exertion so...
