NEW YORK (AP) — Filmmaker Tim Burton has designed a floating freak show of a balloon for this year's family-friendly Macy's Thanksgiving Day Parade in New York City.With pointed teeth and jagged stitching across his face, B. is the Frankenstein of balloons.A Burton-created backstory distributed by Macy's says the balloon boy was "stitched together from rejects of old birthday party balloons." The parties were thrown for children at a London hospital. But B. wasn't allowed to join in the fun. Instead he watched the French short film "The Red Balloon" repeatedly.B.'s only dream was to fly and make a child happy — just like in that movie.Now B. will get his chance at November's parade through Manhattan.Burton has directed several films, including "Edward Scissorhands," ''Alice in Wonderland" and "The Nightmare Before Christmas."
