6 Foot Cockroach

A man was sitting at home one evening, when the doorbell rang. When he
answered the door, a 6 foot tall cockroach was standing there. The cockroach
immediately punched him between the eyes and scampered off.

The next evening, the man was sitting at home when the doorbell rang again.
When he answered the door, the cockroach was there again. This time, it
punched him, kicked him and karate chopped him before running away.

The third evening, the man was sitting at home when the doorbell rang. When
he answered the door, the cockroach was there yet again. It leapt at him and
stabbed him several times before running off. The gravely injured man
managed to crawl to the telephone and summoned an ambulance. He was rushed
to intensive care, where they saved his life. The next morning, the doctor
was doing his rounds. He asked the man what happened, so the man explained
about the 6 foot cockroach's attacks, culminating in the near fatal
stabbing.

The doctor thought for a moment and said, "Yes, there's a nasty bug going
around."
