And what makes this movie laugh out loud funny, is that they aren't as concerned about the aliens in the flying saucer as they are that the girl's boyfriend might find out that she had a one night stand (probably after some heavy drinking, since neither can remember if they "did it" or not) with the guy still in her apartment when her boyfriend arrives shortly after they wake and discover the flying saucer. A third comic element, besides the saucer that no one is panicking about, and trying to keep the boyfriend in the dark, is that the weird nerd next door, who wants the girl too, inadvertently finds out about the one night stand, and threatens to tell the boyfriend. How the story progresses from here is what makes it hilarious. What makes it sweet is how the three males involved solve their problem and prove their love for the girl, each in their own way. And what happens with the flying saucer? You'll have to watch to find out.
