Man: Well,I'd like to report a UFO sighting. Police Officer: A what? Man;What do you mean“what”?An unidentified flying object! Police Officer: Wait,tell me exactly what you saw. Man: Well,I was driving home from a party about three hours ago,so it was about 2:00 AM,when I saw this bright light overhead. Police Officer: Okay. And then what happened? Man: Oh,man. Well,it was out of this world. I stopped to watch the light when it disappeared behind a hill about a kilometer ahead of me. Police Officer: Alright. Then what? Man: Well,I got back in my car and I started driving toward where the UFO landed. Police Officer: Now,how do you know it was a UFO?Perhaps you only saw the lights of an airplane,or the headlights of an approaching car. Things like that happen. you know. Man: Well if it was that,how do you explain“the BEAST”? Police Officer: What do you mean,“the BEAST”? Man: Okay. I kept driving for about five minutes when all of a sudden,this giant,hairy creature jumped out in front of my car. Police Officer: Oh,yeah. Then what? Man: Well,then,the beast picked up the front of my car and said,“Get out of the car. I'm taking you to my master!”Something like that. Police Officer: Wow?A hairy alien who can speak English!Come on! Man: I'm not making this up,if that's what you're suggesting. Then,when I didn't get out of the car,the beast opened the car door,carried me on his shoulders to this round-shaped flying saucer,and well,that's when I woke up along side the road. The beast must have knocked me out and left me there. Police Officer: Well,that's the best story I've heard all night,sir. Now,have you been taking any medication,drugs,or alcohol in the last 24 hours?You mentioned you went to a party. Man: What?Well,I did have a few beers,but I'm telling the truth. Police Officer: Okay,okay. We have a great therapist that deals with THESE kinds of cases. Man: I'm not crazy. Police Officer: Well,we'll look into your story. Thank you. (23)
