A man joins a soccer team and his new teammates inform him, "At your first team dinner as the new guy, you will have to give us a talk about sex." The evening arrives and he gives a detailed, humorous account of his sex life.
When he got home, his wife asked how the evening went and not wanting to lie, but also not wanting to explain exactly what happened, he said, "Oh, I had to make a talk about yachting."
His wife thought this a little peculiar but said nothing more and went to sleep.
The next day she bumped into one of his new teammates at the supermarket and asked, "I heard my husband had to make a speech last night. How did it go?"
His mate said smiling, 'Oh, it was excellent! Your husband is clearly very experienced!."
The wife looked confused and replied to his mate, "Strange, he has only done it twice and the second time he was sick."
