TRUE STORY!!!
My son came home from school (first grade) and had the nerve to tell his Mother that he was going to hit her in the nuts! She was, of course, extremely upset and called me at work, letting me know I had the responsibility to take care of this mess. When I got home, I explained the whole "women don't have nuts" first, asked him where he heard the phrase etc.....after a lengthy discussion my boy looks at me, and with all seriousness asks:
Should I have said balls?
