something i just noticed on "jack's uncle"

I was watching my tape of "Jack's Uncle" the other day, the ep where Jack's uncle Freemont comes to vist and passes a bad check to mr. roper to cover the rest of the trio's rent. Anyways, i noticed something really strange. Uncle Freemont comes when Jack, Janet and Chrissy are getting ready to go to the beach so they won't be home when Mr. Roper comes for the rent (Janet and Chrissy are in their bathing suits.)Then Mr. Roper comes, asks for his rent, and Uncle Freemont gives him the bad check. Then there's a commercial break. as the show starts up again, jack is in the kitchen telling his uncle he made a big mistake and they have 2 get the check back somehow. After that scene, they go into the living rm, where they meet Janet and Chrissy, who have changed out of their bathing suits and into regular clothes. U would think that they had changed after the screen faded into that first commercial break, but if you look closely, after the commercial break when Jack comes into the kitchen to talk to his uncle, the door swings and you can see Joyce and Suzanne walking towards the girls' bedroom (it looked like Joyce's arm was around suzanne ). and they still had the clothes on that they were wearing before the commercial break, their bathing suits! and then, like, 2 minutes later they come out wearing different clothes. I thought that was really weird, how could anyone get changed so quickly?

Sometimes they have stage hands help them change in between their scenes. Suzanne and Joyce most likely had something on under their bathing suit, not the entire thing they were wearing when they came back out but undergarments.....I'm confused!

Yeah it is confusing..They probably just put their clothes on over the bathing suits... or something.But still, that's awfully fast.
