Invite them to your place to return their hospitality, and serve them veal, or better yet, boar meat that you hunted and killed yourself! That may be a culinary experience they would be unfamiliar with...
While they're there, show them your gun collection, Marine ribbons, and your collection of Ann Coulter and Tom Clancy books, which are right next to a well-worn Bible. You might ask them if they want a "Rice for President '08" bumper sticker for their car...
You may not get invited back to their place again, though...
