Joke of the Day - Why you should do it once a year

A therapist has a theory that couples who make love once a day are the happiest. So he tests it at a seminar by asking those assembled, 


“How many people here make love once a day?” Half the people raise their hands, each of them grinning widely. 
“Once a week?” A third of 
the audience members raise their hands, their grins a bit less vibrant. “Once a month?” A few hands tepidly go up. Then he asks, “OK, how about once a year?”

One man in the back jumps up and down, jubilantly waving his hands. 

The therapist is shocked—this disproves his theory. 
“If you make love only once a year,” he asks, “why are you so happy?”
The man yells, 
“Today’s the day!”
