Meatball

In Meatball from 1972, Harry Reems stars as Dr Schmock, a zany mad scientist who accidentally discovers Preparation X. It's a formula that can make an ordinary meatball swell into twice its normal size. But whenever a guy eats it, it also has a similar effect on him too! The good doctor tests out his creation and ends up with a constant erection that even his sexiest assistants can't calm down.
