Exciting as watching a...hole in the wall?

I just read a Japan Times article about how a certain show has taken off and caught the interest of foreign TV execs. You know, I've seen the show before, and I did find it pretty amusing. But you gotta ask yourself if this is a good idea. Compared to other Japanese TV shows, yeah, maybe this thing is gold. But compared to British or American programming? I'm not so sure.

The idea is novel, but I'm not sure - how long could a show like this really go on? Could something like this really run for more than a season? A show about guys in spandex trying to fit themselves into holes in a wall? But then maybe I'm giving the average TV junkie too much credit.
