Late one evening, Norm’s doorbell rang.

When he answered the door, he found a six-foot-tall cockroach standing in front of him. The bug grabbed Norm by the collar, punched him in the eye, threw him across the living room and then ran off.

The next day, Norm went to see his doctor to have his bruised eye examined. “Ah, yes,” the doctor said when Norm explained what had happened to him.

“There’s a nasty bug going around.”
