Microsoft Spell check, part II

So I'm performing a spell check of the post "This is just plain nuts," and I realize that apparently, everyone who worked on MS Windows Spell Check failed anatomy. The system doesn't recognize either "cranial" or "genitals." In fact, when the latter word came up, the suggestions given were:
gentiles
gentlest
gondolas

So, when somebody mentions someone who is uncircumcised, you'll now know why they're called gentiles!
