I think this all the time. Try going in pitch black with a picher of water, a flashlight, and a bowl. As you pour the water in to the bowl shine the flashlight across the water. It will move sightly with the light.
I appreciate someone going through all this trouble to help someone spot the alien, but I still can't seem to find anything out of the norm. Perhaps a couple more arrows directing me where exactly the alien is located would help.
That one time i tried to tell my sister about when teachers bend over to help the person next beside you and his ass be poppin, the joke was "next time he do this imma eat his ass he gotta LEARN to not do it again." but i was laughing too hard.
I had a friend who did this once and they had the exact response, "abort mission!" I've also tried this with the same exact ending, except no picture was taken because I couldn't get one without the idiot looking.
