You can potty train them in one marathon session even if they don't need to go. Just stack potty training five times (sometimes genius' will learn in four sessions but five is the normal). The potty will overflow about the third time but just leave it until you are done, then mop and empty once they are trained. Then move on to talking and leave walking for last. Talking seems to go faster (to me) since it is just sitting and talking while walking involves picking up and standing up and backing up and waiting.
