Preheat the oven. Set to Broil and position oven rack on second closest level to the top. Cook corn cobs, including husks, in microwave on high for 6 minutes. Let stand for 5 minutes. Remove the husks. Sprinkle the chili powder over the cobs. Place cobs in a pan lined with aluminum paper. Lightly pour the tequila over the cobs, then and sprinkle with cheese. Broil cobs in the oven for about 5 minutes or until the cheese gets golden, crusty brown. Just before serving, squeeze lime juice over each one.
