I know this is random, but some people think it's really had to cut an avocado, so I had to share the knowledge. :-)
First, cut it in half and cleanly remove the seed. Then score it like this--be sure to cut from the top all the way down to the skin of the fruit, but don't cut through the skin:
After you've cut it, push up at the center from the bottom. What will happen is that the pear will start to separate from the skin:
Keep pushing and you will get this:
And you're done. See, that wasn't so hard!
