It's not that Edd has saved 'many' people, I think the count is three now.

C'mon folks... if you're out there, untrained, looking at the entrance to one of these and contemplating if Edd's so good he might go for four, you might better just wait until after you win the powerball.
There's a sign right there in the thing, it tells you what has happened time after time before you. This time it's talking to you, and it's really, really, not a joke.
