Bleen is a concoction created by Kelly in a lab, during her study to play Madame Curie in a commercial. It is categorized as a level three bio-hazard and they demand she take it from the lab. She puts it in Al's shower where Al uses it as shampoo. It causes Al's hair to grow and makes him attractive. The rest of NO MA'AM test it and get the same result. They learn, however, that it makes them find their wives sexually attractive, a notion which disgusts Al. To avoid having sex with their nagging wives, he bans Bleen and has Kelly make a cure.
