Petticoat Junction stars Lori Saunders and Meredith MacRae
This one may seem a bit weird since they played sisters on TV, but it's not like they were sisters in real life....Isn't it fun to think that they gave each other a look filming that water tower opening, realized how beautiful they both were (especially the gorgeous Lori Saunders) and decided to go back to the dressing room to get to know each other better? Actually, Meredith joined the show after Lori, so Lori could have welcomed Meredith to the show by welcoming her into bed.
For those who don't know which one is who:
Lori Saunders (the brunette)
Meredith MacRae (the blonde)
