Danny Fantom Sezon 1 Odcinek 13: "13"

Jazz falls for a hunky boy ghost - Johnny 13 - who has the power to cast his shadow out and create bad luck for everyone who crosses him, especially the girls he's dating. Danny finds himself in the uncomfortable position of behaving like an overprotective parent, much to Jack and Maddie's pride and Jazz's fury. Danny has to beat Johnny back into the ghost zone before Jazz fully accepts Johnny's offer to go steady - or else!
