I didn't think it would work or be easy, but hey, if Alton Brown suggests it, I gotta try it!!!
I watched his "Down and Out in Paradise" a couple of days ago where he was supposedly stranded on a deserted island (ended up being Oahu

), and he said the easiest way to "carve" a pineapple is to take an electric knife to it. Well, I just bought a fresh pineapple at the grocery store today (craving fresh fruit

), and I decided to try it. My electric knife only gets used to carve a Turkey at Christmas, so I thought, why not?
It worked like a breeze!! Cut the ends off, slice the rind off, and then cut it when it's on its side, into rings. Then you cut the core out with a pastry ring (I don't have any, so I just used a knife), then slice into pieces. EASY AS PIE! Or PINEAPPLE pie!

Took me about 5 minutes.
