I've been handed some pretty crazy burger-centric gifts over the years, everything from hamburger soap to the now-famous hamburger phone. Every year our Christmas tree is filled with an assortment of hamburger ornaments and my daughter just gave me a burger-shaped eraser from Japan. A recent gift from my father-in-law may have taken the prize however. On a trip to Bolivia last month he spotted this familiar looking rock in a riverbed. He told me, "I immediately thought of you." I wonder why?
