Like Father Like Son 1987 VHS Dudley Moore Kirk Cameron

Chris Hammond is a high school senior. He likes a girl at school, Lori, who is dating his rival and bully Rick. His father, Jack, is a surgeon who is trying to get promoted to chief of staff at his hospital. Chris has a friend, Clarence "Trigger", whose Uncle Earl had his leg fixed by Native Americans with a body-switching potion called the "Brain-Transference Serum". Trigger shows Chris how the serum works by trying it out on Chris' cat and dog, and the pets switch bodies. Trigger brought the serum in a Tabasco sauce bottle, and the Hammond's housekeeper Phyllis puts the bottle in the food cupboard. Jack unwittingly puts some serum in his Bloody Mary. The serum works by someone ingesting it, then the next person that looks into their eyes switches bodies with them. As Jack looks into his son's eyes, the father and son switch bodies.
