I would add: after you get the top, bottom, and skin/eyes off, cut the pineapple in half top to bottom, then cut each half top to bottom so you have quarters. Stand each quarter on the bottom edge and cut the hard central core out (occasionally you`ll get one that doesn't have a woody core but in my
experience it's almost always worth doing).
Save the skins, cores, etc and freeze them. Next week, after you've eaten your lovely pineapple and almost forgotten about it, blend these frozen bits with water in a blender. Add a handful of some kind of mint if you have any in the garden and it's to your taste. Strain out all the fibers (the juice will be FOAMY), add some sweetener, and you've got some great juice.
(edited to add: my mother in law takes the skins/eyes/cores and boils them in some water, strains out all the stuff without blending when cool, and adds sweetener, which makes a different kind of great juice or even a super additive for cocktails/mocktails/tea/etc)
