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 Frank didn't drink at all. The doorbell rang. The cockroach was standing there. The bug beat the snot out of Frank and left him in a heap on the living room floor.
The following day, Frank went to see his doctor. He explained 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."
