Chances are Battle: Los Angeles won't end with a scene like this one, but you never know. So why exactly is that kiss electrocuting the alien woman? Is it just really strong static electricity?
The clip comes from the ultra-goofy Invasion of the Star Creatures, in which it's up to these two grunts to put a stop to the alien invasion, by teaching the aliens about love. Oh, and by sabotaging their spaceship. Any aliens who are able to invade Earth wearing spike heels and bathing suits, and mustering an army of plant dudes, deserve some props though.
