I think a Swiss fortune cookie would say something like "Grüezi! Diin Huus wärda rächtig riin und diin Gält sichr sy", which means "Your house will be clean and your money will be secure in a vault."
Edit: Um, you don't have to translate it into the foreign language, just saying it in English is fine. I just had the urge to cobble up some Schwyzrdüütsch there, that's all. :}
