Debbie and Marsha had the unexplainable ability to trade body parts.
When Debbie sprained a wrist before a basketball tournament, Marsha swapped wrists with Debbie.
And when Marsha had a rough period before a gymnastics tryout, they traded vaginas.
Whenever one needed the other, she was there, literally lending a hand or whatever was needed.
They found a lump in Marsha’s breast after she had a baby.
Debbie underwent the double mastectomy for her.
They take turns feeding the baby.
After all, with the constant swapping between them, they’re not really sure which one of them is the true mother.
