I'm a bit fearful of helicopters flying over at night. They don't bother me in the daytime 'cause I can look up and see that they are, in fact, helicopters. But at night, I wonder if they're real helicopters or alien spaceships. Yeah, I know alien spaceships are supposed to only emit a low hum, but don't ya think a critter smart enough to fly here from light-years away might be smart enough to disguise his spaceship by making it sound like a helicopter?

And even if they are real helicopters, how do I know they aren't out looking for an alien spaceship that may have crash-landed in a neighbor's cow pasture or peanut field?

And even if they aren't looking for crash-landed aliens, how do I know the pilot isn't some hot dog who's gonna use my house for target practice?
