There’s an old Southern Baptist joke: A teacher told her students to bring in symbols of their faith for show and tell. Johnny is Catholic and shares a crucifix. Suzy is Jewish so she presents a Star of David. The teacher is confused, though, to find Bobby holding a casserole dish. “What religion are you, Bobby?” He replies, “Oh, I’m a Baptist!” The joke gets repeated in sermons and online because we Protestants still love our covered-dish meals.
