Joan was beginning to panic. She COULDN'T be a penis! It just wasn't possible!
But she was, and she had no illusions what Danny was going to do with her. It was supposed to be impossible, but too much had been done with the stone already for her to have any illusions that what was about to happen couldn't be stopped... and that it would last a long time. And that unless something happened soon, she was going to be stuck as Danny's penis forever.
Patty wasn't taking her clothes off, forcing Danny to do it for her. He wasn't neat, he unbuttoned, pulled, unzipped, and pulled some more wherever necessary, until... 'HEY!'
Joan knew that sound, that was Karyn complaining, telepathically. Danny must have heard it too, because he jumped slightly, "What?"
Patty spoke next, "Don't worry about it, just throw it away."
Before Danny could do so, Joan put her plan into action, "I WISH PATTY AND I WOULD SWITCH BODIES!"
