Joe stopped off at the local grocery store like he had so many nights before. He bought two six packs of beer and took them home. When he got home, he slowly drank each of the beers. Shortly after he finished the last one, he heard a knock on his door. He opened the door and found a 6-foot tall cockroach standing there. The cockroach grabbed Joe and threw him across the room against the wall, walked over and hit Joe square in the mouth and turned around and left.
The next night, Joe stopped and bought his usual two six-packs of beer. He got home and, after drinking eight of the twelve, he heard the knock on his door. He opened the door and again stood face-to-face with that same six-foot cockroach. This time the cockroach hit Joe in his stomach as hard as he could and left Joe laying in a heap on his living room floor and walked out.
The third night, Joe again stopped to buy beer, but this time only bought one six pack. He was sitting at home drinking the beer and when he finished the last one, again there was that familiar knock on his front door. Again when Joe opened the door, there was that six-foot cockroach. This time it kneed Joe in the groin and hit him as hard as it could on the side of Joe's head, leaving him knocked out in the middle of the floor. The cockroach walked out.
The next day, Joe went to see his doctor. He explained everything that had happened the previous three nights. He was scared. He asked the doctor what to do.
The doctor looked Joe in the eye and said, "Don't worry, there's just a nasty bug going around. "
