Three men are talking : a programmer, a doctor, and a lawyer.
the lawyer says,
"man, the only way is to have a mistress.
with all these divorce suits, it's terrible."
the doctor says,
"are you kidding? with all the stds out there,
you want a wife and that's it."
the programmer says,
"you need both a wife and a mistress.
because when you're not with the mistress,
she'll assume you're with your wife,
and when you're not with your wife,
she'll assume you're with your mistress,
and that leaves you more time
to be in the lab programming!"
