Johnny's New Baby Sisters is the first part of 40th episode, the first episode of the fourth season and the 79th episode over all.


Hugh and Lila are going out for dinner and watch a girl movie Hugh will hate and they left the kids in charge until they get home in three hours.

Susan and Mary accidentally turn themselves into twin babies so Gil who started his own babysitting service could take care of them. However because Gil is so irresponsible Johnny winds up having to take care of baby Susan and Mary himself with some help from Dukey. This includes feeding them, changing their dirty diapers and keeping them out of trouble. Things get even more out of control when Bling Bling pays an unexpected visit and agrees to help take care of them in exchange for getting to spend time with baby Susan. Unfortunately, though, doing all this ends up interfering with an awesome party he and Dukey had been planning to throw where they relax, eat junk food and watch TV all day. Johnny attempt to turn them back to normal with their machine but can't since he doesn't know the code. It is only after warning them that their parents are coming home early and that they'll be in trouble if they catch them as babies do Susan and Mary give him the code to turn them back into teens again. Then the four of them along with Bling Bling quickly tidy up the house just as their parents get home.

They almost get away with it when the baby food and diapers they stuffed in the couch get thrown back out all over the place and Gil makes a comment about their new babies and this causes Hugh and Lila to get mad at Johnny and the girls. And the kids all said, "Oh. So close!", (it can be presumed that the kids might get grounded for this).
