It was a horror movie called The Manitou and ended with our naked heroine sitting on a hotel bed, her body hooked up to the hotel power supply, zapping the monster with lightning bolts from her fingertips. Yeah, right! I don't know how the actress kept from laughing. We couldn't.
BTW did you know that a teacher once told his class, "Two negatives make a positive but two positives can never make a negative." And one of the kids said, "Yeah, right!"
