Only an insane man pursued a course that would lead to destruction.

At the start of the fifteenth century it housed just six insane men.

The insane man scrambled in, and the car was off.

Only insane men would do the things they did.

"Does that sound like the utterings of an insane man?"

Now go back and talk about reality with the other insane men.

An insane man in deep space could be deadly to everyone around him.

He wanted to believe it, as far at least as a man nearly insane with jealousy could be expected to.

I could almost make myself believe that this insane man wasn't my husband.

"Well, for an insane man, he certainly seems to have done wonders here."
