Let me tell you why not...first, I nearly severed a piece of my finger trying to cut them in half. It was like trying to saw through a boulder. Once I did manage to cut through them, I was faced with nasty piles of guts and seeds. I am seriously repulsed by those types of things (which is why I have successfully avoided pumpkin carving every year). The initial scoop of guts & seeds wasn't bad, but I had to do a lot of digging/scraping to get all of the strings out. GAG.
THEN, after I baked them for almost an hour, I had to peel off the skin and remove all of the "meat" to blend up. Again, it was just really gross to me. And not an easy task, that skin is stubborn.
