Nope, the spoon is simply NOT a fork. I suppose that he could have gotten a huge butter-knife, but those are difficult to carry around (as diminutive as Phil is, he wouldn't be able to manage it). As was pointed out by another post, the hellish trident that Satan is depicted with is the basis for Phil's spoon. Since the big-guy is the "prince of darkness," and Phil's the prince of insufficient light," then the spoon is applicable. Personally, I think it should have been a huge plastic spork (like the sort you get with an order from Kentucky Fried Chicken).
Yes, I remember Phil now. I guess being the "prince of insufficient light" means that he's perfect for the job of vice-president of marginally legal activities. Being assigned president and CEO of the entire company would be WAAAY over his head.
