My Penis Is Gone. It's a Mechanical One

Tony's wife went downstairs. And pointed out to John that his penis was still intact. So which is weird, right? Well, yeah. He looked at it closely and saw that the extraterrestrial had replaced his normal human penis with a mechanical version. That happens to all robotic penises. They just break. An hour later, after the effects of K wore off, Lily found his normal human genitalia in place of the mechanical one exactly where it had always been.
