A man is sitting at home one evening when the
doorbell rings.

When he answers the door, a 6 foot tall cockroach
is standing there.

The cockroach immediately punches him between
the eyes and scampers off.

The next evening, the man is sitting at home when
the doorbell rings.

When he answers the door, the cockroach is there
again.

This time, it punches him, kicks him and karate chops
him before running away...

The third evening, the man is sitting at home when
the doorbell rings.

When he answers the door, the cockroach is there
yet again.

It leaps at him and stabs him several times before
making off.

The gravely injured man manages to crawl to the
telephone and summon an ambulance.

He is rushed to intensive care and they save
his life.

The next morning, the doctor is doing his rounds. He
asks our hero what happened.

The man explains about the 6 foot cockroach's attacks,
culminating in the near fatal stabbing.

The doctor thinks for a moment and says, "Yes, there
is a nasty bug going around."
