Mary was about to choose the donkey vial and then she noticed one she hadn't before... Silver-Back Gorilla.
Hmmm... that would certainly be interesting. She pours half of the vial in so John won't completely transform into a Gorilla. He should change so that he gets some of the best features without losing that nice bulge in his pants.
She puts the stopper on the vial and retuns it to it's place.
She pours herself a glass of red wine and brings John his soda.
Mary invites him to dinner and offers him some of the pizza he delivered. He sips his soda as he eats. John accepts and mary watches as the pimples begin clearing, she watches as hair begins to grow on his arms and his skin starts to darken.
John, being very thirsty, downs his cold soda in a few minutes. Then, he feels his clothes becoming too tight...
