Similar gag to the one about the guy who was to give a presentation to his local Rotary Club. He told his wife it was going to be about sailing,but at the last minute he thought it would be too boring so he talked instead about sex. The day after the talk, the wife met one of the Rotary Club members who said how much he had enjoyed hubby's speech. She said she was surprised at his choice of subject, as he'd only done it twice. The first time he vomited and the second time he lost his hat.
