So there’s an NBC show called “American Ninja Warrior”, that is a mimic of a Japanese show called “Sasuke” (Ninja Warrior). It’s basically a really tough obstacle course for adults, and only the best of the best make it through the several different stages.
This is most likely staged to get internet views and publicity for a show that may have been faltering. Regardless, it is pretty incredible that he completed these tasks, being naked is just the cherry on top. It’s especially obvious that it was staged because the commentators had penis-puns prepared. Lame sauce.
Anyway, it’s fun and it received over a million views. Good job, NBC.
