If desired, trim and discard ends from zucchini. Cut zucchini in half lengthwise. Cut a very thin slice off the bottom of each zucchini half so it will sit flat. Scoop out pulp, leaving 1/4-inch shells (reserve the zucchini pulp for another use).
For filling, in a large skillet heat oil over medium heat. Add corn; cook about 5 minutes or until tender, stirring occasionally. Cool. In a large bowl combine cooked corn, 1/2 cup of the cheese, the sour cream, garlic, and hot pepper sauce.
For a charcoal or gas grill, place zucchini, cut sides down, on the rack of a covered grill directly over medium heat. Grill for 8 minutes. Remove from grill. Spoon filling into zucchini shells; sprinkle with the remaining 1/2 cup cheese. Grill about 8 minutes more or until zucchini is crisp-tender and filling is heated through. Sprinkle with paprika.
