Janet had been awake for some time, but had found herself utterly unable to speak. Her brain had been surgically transplanted into the hairy body of a young, male chimpanzee named Bobo. Now in his animal body, she was naked and strapped down to one of the lab tables. She even had a gag of some kind in her mouth, presumably to keep the originally Bobo quiet before the operation while the professor's sedatives were still taking effect.
The professor carefully removed the gag from Janet's mouth.
“How do you feel?” he asked.
“Ooog ack-ack, AIIGG!” screamed Janet.
She still possessed her own consciousness, but the clumsy chimpanzee body she was trapped in lacked the muscle coordination necessary to use lips, tongue, mouth, and vocal chords in creating speech.
“Fascinating,” noted the professor, furiously jotting down notes in his clipboard. After several minutes of Janet's wild, animal screams, the professor replaced the gag in her mouth and moved on to examine Bobo – now in Janet's human body.
“Bobo?” the professor softly asked. He gently touched the shoulder of Janet's body trying to rouse the creature from sleep. Abruptly, Janet's body opened its eyes and looked nervously around the room.
“It's me, Bobo,” said the professor in a calm, soothing voice. “I did exactly what I promised I would do. Now, do you remember our conversation from earlier? What did I promise to do for you? You may speak, Bobo. Please go ahead and use your words.”
Janet's body thrashed about for a moment, struggling against the restraints that pinned it to the table. Finally, it stopped trying to move and looked up at the professor expectantly.
“You must use speech,” said the professor. “Can you speak, Bobo? You must try. It is vital to this experiment. What did I promise you?”
“Mah-Mah-Mah...” stuttered Janet's body. “Me... Me... Me... mah-make... oo-man. Oo-man. Mah-make oo-man, me!”
“Splendid!” laughed the professor. “Keep practicing Bobo, and you'll get it yet. Ah, this is wondrous! I successfully taught you English while still a chimp, and now that you have the body of a human being, you are able to actually speak! Oh, how exciting this is! Keep practicing, my boy... erm... girl, I guess I should call you now. You'll get better at it with time. Here, why don't you come be my lab helper, Bobo. Just like old times.”
Janet, still bound and gagged in the hairy chimp's original body could only stare with terrified horror as the professor un-bound her old body and began leading it around the laboratory. Bobo, in Janet's old body, lumbered along low to the ground, with a wide-legged crouching stance, dragging his knuckles behind him and occasionally stopping to scratch curiously at his new, empty crotch and his new, heavy, fat breasts.
“Yes, yes,” said the professor. “You're a woman now, Bobo. It couldn't be helped. You'll adjust. Your name is Janet Donaldson. Can you say that?”
“M-M-Me Ja-Ja-Jaaa-net!” exclaimed Bobo with Janet's voice. “Me Ja-Jaaaa-net! Me Janet! Me Janet!”
“Yes,” smiled the professor. “And she is now a monkey.”
