It's easy. Well, it's way too easy here in Georgia. Since we're at the bottom of the list when it comes to education (the main reason here being that the school board is forcing teachers to pass everyone no matter what), just say "one of them big and fancy words, yeehaw!" and you confuse them while walking away smiling. I once scared a stripper by telling her after getting a dance that I have Epidermis. It's contagious and she needed to get checked out. I finally told her it means skin. Awesome.
