Cook noodles according to package directions; drain. In a large skillet, saute celery in 1 tablespoon butter until tender. Stir in cream cheese and milk; cook and stir until cheese is melted. Add noodles, ham, pineapple, worcestershire sauce, salt and pepper.
Transfer to an ungreased 1 1/2 quart baking dish. Melt remaining butter; toss with bread crumbs. Sprinkle over top. Bake, uncovered, at 350 for 30-35 minutes or until heated through.
