uh-oh. this is not good.
what do you mean?
the aliens' scouting force left this message. we found it just in time.
what should we do?
we gotta change the message.
how are we gonna do that?
just re-arrange some of these rocks.
what'll that do?
maybe send them to wal-mart instead of the white house.
I don't know if wal-mart would like that.
well, that depends on if the aliens like to shop, doesn't it?
