In Feasting with God: Adventures in Table Spirituality, Holly W. Whitcomb provides plans for "An Outrageous Feast" designed to help us get in touch with our most flamboyant selves. Guests wear outrageous costumes and bring an outrageous food that speaks of excess — the creamiest cheescake, the pizza with the most toppings. Everyone shares an outrageous fantasy and commits to doing one outrageous deed for the common good.
Spend an afternoon at the local playground. Get to know your neighborhood better by trying out its toys.
Create a "Fools Festival" for a group in your community, perhaps a ward at the hospital or a nursery school. Wear humorous outfits and take the makings for more. Paint each other's faces. Tell jokes and put on skits. You might plan all this merry-making for April Fool's Day.
