It could also be a broken insulator. Ive done that one before. If its arcing around through the boot then youll most likely want to buy new plug wires. That one is most likely carbon tracked by now.

Ditto on the arcing. You either have a bad plug wire or it is not snapped on all the way as mentioned above. The wire may be salvagable if you are sure it is pushed on all the way. You can expose the clip by sliding the boot away and squeeze on it so that there is a better contact on the end of the plug. Repeated removal and installtion of plugs wires expands the little cup clip (why can't I remember what this thing is called?) in the wire.

If it was sparking at the point where the porcelain meets ther metal plug portion, it sounds like a cracked insulator on the plug (possibly from dropping it or torqueing it down too tightly.
I'd replace that one plug and try it again.
