First, rip off the top. Trust me, it's not that hard :)
Then, slice off the top and bottom so you have a flat surface
Next, slice off strips of the rind all the way around
You then have all these little eye things, so...
You have to pop 'em out. Sounds violent, I know. But you have to do it unless you enjoy tearing your tongue to shreds while you're eating. Which I do not.
When you are finished de-eyeing your pineapple, cut it into halves
And strip the core. You really just have to take off a little bit.
Finally, cut into cubes. Ta-Dah!
