How many things WRONG do you see with these videos?

1.  Standing up, yelling and giving away your position.
2.  Having your buddy standing up even higher, to film your demise.

Why don't they walk on the top of ridges and holler, sing songs, etc., if they want to be die, instead of sneak around in ditches and just about the time they're out-of-sight, jump up and start screaming?
