Forgot the name of a script!!

Its about a little boy whos obsessed with Superman his parents own a funeral home in the first floor of their home where he meets a little girl who likes him. The little boy gets into some sort of accident and ends up in the hospital and she takes him a piece of kryptonite as a present but he freaks out as its Supermans weakness in the end he kinda starts to like the little girl too. I saw this as a one act so there may be more to it. Would love to find out what the title of this script is I have been searching for it for years!!!
