Of course, that would only be the family members I like. For the rest, they can have a crucifix, a fannypack, and a picture of knuckles dragging.

Hey, Machine Elf: How about a large wheel of cheese with a knife slicing through it? With two skunks as upholders and a crest in the form of a roll of toilet paper. And the motto: The Dog Did It Again.
