'well , in this lucky town , right , a lady making , as it might be , a tray of cakes , well , all she 'll need to do is shout down the nearest rat hole and say , `` good morning , rats , there 's one cake for you , i 'll be much obliged if'n you did n't touch the rest of them '' , and the rats will say `` right you are , missus , no problem at all '' .
