A very old joke, but maybe some fun..
> A noted sex therapist realized that people often lie about the
> frequency of their encounters, so he devised a test to tell for
> certain how often someone had sex. To prove his theory, he filled up
> an auditorium with people, and went down the line asking each person
> to smile. Using the size of the person's smile, the therapist was
> able to guess accurately how often each person had sex. The last man
> in line was grinning from ear to ear.Twice a day," the therapist
> guessed, but was surprised when the man said no. "Once a day, then?"
> Again the answer was no. "Twice a week?" "No." "Twice a month?" "No."
> When the doctor asked, "Once a year?" the man finally said yesThe
> therapist was angry that his theory hadn't worked with this
> individual, and he asked the man, "What the heck are you so happy
> about?" The man answered, "Tonight's the night!"
