My doctor told me to stop having intimate dinners for four. Unless there are three other people.

Our reading
An editorial interpretation.
A joke dressed as medical restraint. The doctor's rule against intimate dinners for four sounds sensible until the exception: fine if three other people are there. So the dinner for four is really one person eating alone, and the intimacy is just cover.
