What Woody Allan movie includes the joke about the couple who go to
therapy and the woman says "We're always having sex. Twice a week" and
the man says "We hardly ever have sex. Twice a week"?

This comes from the 1977 movie "Annie Hall", which stars Woody Allen
as Alvy Singer and Diane Keaton as Annie Hall.

ALVY'S PSYCHIATRIST
How often do you sleep together?
   
ANNIE'S PSYCHIATRIST 
Do you have sex often?
   
ALVY 
Hardly ever.  Maybe three times a week.
   
ANNIE 
Constantly!  I'd say three times a week.  
Like the other night, Alvy wanted to have 
sex.
