Cut two individual-size 4-ounce cartons of vanilla ice cream in half crosswise to make 4 disks; freeze 30 minutes. Pulse 2 cups white bread cubes and 2 cups shredded coconut in a food processor, then spread on a plate. Remove the cartons and press the ice cream into the crumb mixture, covering all sides (reserve the remaining crumbs). Freeze until hard, 1 hour. Meanwhile, make the "tartar sauce" (below). Dip the disks in 3 beaten eggs, then press in the reserved crumbs and freeze at least 1 more hour. Heat 3 inches of vegetable oil to 350 degrees F in a deep skillet and fry the ice cream until golden, 2 to 3 minutes. Drain on paper towels, then eat immediately.
