Earl won first prize at a Opening Day tournament which was an envelope.
When he opened the envelope, he was very surprised to find a voucher for a free visit to a brothel. As he had never been to a brothel before but he decided to go the next day.
The girls were very friendly and soon he found a lovely young lady and went with her to her room. Five minutes later, she came running to the Madam and asked, "Can you tell me what a Mulligan is?"
