This guy is sitting at home one night when there's a loud knock on the door. The man answers the door and is surprised to find that there's a six foot tall beetle standing on his doorstep.  Before the man has time to speak the beetle launches a frenzied attack on him and after a flurry of blows it leaves.

The man is covered in cuts and bruises and immediately goes to see his doctor. On seeing him, the doctor asks, "What happened?"

The man replies, "You won't believe me. I was beaten up by a massive beetle." On seeing that his doctor is nonplussed by this the man asks, "Well, aren't you surprised?"

The doctor replies, "Not really. There's a nasty bug going around."
