After Dinner speaker
A guy with a reputation as a brilliant after-dinner speaker was asked to speak at his local rugby club annual dinner. When his wife found out about this she asked him what he would be speaking about.
"Oh, I'll be talking about sailing."
When the time came, as it was the Rugby Club and most of the audience were quite merry, he announced that in a change to the advertised programme the subject of his talk would be "My Sexual Experiences". Unsurprisingly, the speech went exceedingly well and was much appreciated by his audience.
A couple of days later, one of the rugby players met the speaker's wife and said, "Hey! That was a great speech your hubby gave at the dinner the other night!"
"Really?" said the wife. "I am surprised. He's only done it twice. The first time he was sick and the second time his hat blew off!"
