Repeated Knocks !

There is a knock on St. Peter's door. He looks out and a man is standing there. St. Peter is about to begin his interview when the man disappears.

A short time later there's another knock. St. Peter gets the door, sees the man, opens his mouth to speak, and the man disappears once again.

A few minutes later, another knock. Once again St. Peter opens the door and sees the same man.

"Hey, are you playing games with me?" St. Peter calls after him.

"No," the man's distant voice replies anxiously. "They're trying to resuscitate me."
