An interesting tale to listen to.  I supposed that Johnny Promise knew that his friend wasn't well hinged and that just telling him about his revenge would drive him over the edge.  Perhaps he didn't think it would take three years to do so, but he probably knew it would happen.  I did like the daylight savings time making the difference (even though it's changed a few times since then, I did like how they said that "back then it was..." - personally I could do without it altogether [perhaps I should move to Arizona]).
