The name "Gadzooks" is an exclamation, It could be in a sentece like "Gadzooks old man, where is that stenchy smell coming from?" or something, I got it from my favourite book in the whole wide world (I also like "Knife, no ordinary fairytail" as well) there's a series, The fire within, Icefire, Firestar, the fire eternal, darkfire etc. (I kind of like mystery books and romance only a little romance tho LOL) Gadzooks is a Dragon in the Icefire book!
