A month in a box? Pagh! Standing on a pole for many days on end? I scoff at you!
Now that is a stunt! Don't try this one at home, kids. Or here, for that matter.
(ADDENDUM: I should note that police here aren't yet convinced, as of this writing, that it wasn't some kind of hoax -- like maybe the guy dressed a blow-up doll in identical clothes and then hung out down below the falls for the appropriate moment to climb out.)
