Severus Snape's Most Embarrassing Day Ever

James Potter's latest prank has Severus Snape in a bind - literally, since Filch left Severus shackled upside-down to the wall in his office. And James's parting gift, an engorgio charm, has Severus seriously hoping nobody sees him. It falls to Lily Evans, Severus's soul-crippling crush, to find him and help him find a way out of his imprisonment - and maybe get a little revenge.
