Robert won first prize at a Father's 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.
He had never been to one before but he decided to go the next day even though he was very nervous.
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?"
