What was the full joke to which the punch-line was "Phyllis Kirk Kirk Douglas Douglas Douglas"?

Long ago, Kirk Douglas appeared on Rowan & Martin's Laugh-In with a quick one-liner in which he hypothesized: "If Phyllis Kirk married Kirk Douglas..." and it ended with "Her full name would be Phyllis Kirk Kirk Douglas Douglas Douglas." But I don't remember the whole one-liner! :-( Does anyone know it?
