The next night, after he finished his 4th beer, the doorbell rang. He walked slowly to the door and found the same six-foot cockroach standing there. The big bug punched him in the stomach, then left.
The next night, after he finished his 1st beer, the doorbell rang again.
The same six-foot cockroach was standing there. This time, he was
kneed in the groin and hit behind the ear as he doubled over in
pain. Then the big bug left.
The fourth night Joe didn't drink at all. The doorbell rang. The cockroach was standing there. The bug beat the snot out of Joe and left him in a heap on the living room floor.
The following day, Joe went to see his doctor. He explained the events of the preceding four nights. "What can I do?" he pleaded.
"Not much" the doctor replied. "There's just a nasty bug going
around."
