I was telling my friends some statistics on how often different groups of people have sex. I told them that I had heard Europeans had sex, on average, once a day. Then I told them that I had heard North Americans had sex, on average, twice a week. Finally I told them Asians had sex, on average, once every six months. These stats surprised my friends who had just now learned they were Asian.
