I'm sure there's life out there somewhere, but I'd feel silly calling it alien.
I saw The Fourth Kind in theaters with a friend, it was hilarious! My favorite part: when one of the therapist's patients has an 'episode', he knocks over a lamp that was on a small table next to his chair. When they resume the therapy later, the lamp and table have been moved to the other side of the room. This is never mentioned or anything, but I still thought it was funny
