Love in the Fast Lane (1987)

This pilot for a T.V. series was never picked up, although it's the prototype for Bill Plympton's much more successful "I Married a Strange Person". It uses the animation style of "Scooby Doo" to tell the story of a newlywed yuppie couple hosting a dinner party for the husband's boss and his wife - only the yuppie wife has just accidentally taken a love potion!
