Pour 2 cups orange juice and 2 cups pink lemonade into a pitcher. Add a small can of pineapple chunks and the juice in which they are packed. Add 1 cup strawberries to the pitcher, taking care to first cut any large strawberries in half. Peel a navel orange. Separate it into sections. Cut each section into thirds, and add them to the fruit punch. Fill the pitcher with ice cubes and stir until the pitcher is frosty.
