Karyn looked at Jack. "I don't see what's wrong?" she said, scratching at her groin.
Jack cupped his breasts in his hand. "Did you make these bigger or smaller?"
"No, I told you. I swapped your heads around."
Jack was confused. "So I had that body? Eeeugh! Disgusting. Fancy me having a penis and flat chested."
"You look so funny," said Jay, sniggering under his breath. "With breasts and everything."
"I don't know what you're laughing about. Your breasts are just as funny."
Jay cupped his breasts in his hand. "I like my breasts."
(NB - As Karyn wished for an exact duplicate of Jon, any changes that happen to Jack also happen to Jay)
Jack grabbed the stone. "Right, my turn. Go out and come in again in a minute."
Jay and Karyn walked out of the room, Jay's boobs bouncing gently in time with his strides. After a short time, they walked back in.
Jack started laughing.
"What's wrong?" said Karyn.
