A vicar is invited to give a talk to the womens institute. The subject is 'The importance of a healthy sexual relationship within marriage'.
The vicar is so embarrassed he tells his wife that the talk is to be about sailing. Anyway he goes to the institute and his talk is a resounding success. A few days later the vicars wife and the the leader of the womens institute meet whilst out shopping and the leader is very effusive about the vicars talk.
'Well I dont understand how he thinks he knows so much about the subject. He's only ever tried it three times, the first time he gave up after bungling around for half an hour, the second time he got soaking wet and the last time his hat blew off'
