This fact come from here.
While living in England, Harris popped out for milk and when seeing the paper he noticed that Young Munster were playing in Thomond Park, Co. Limerick, Harris got the next available flight to Ireland. He spent the following 3 weeks on a drinking binge. All was unknown at the time to his wife, who had no idea where he was. When he finally returned to England, he rang the doorbell of his house. His wife answered the door and before she had a chance to say anything, he said "Well, why didn't you pay the ransom?".
