 Before she dies, Julia is seen waitressing at "The Purple Onion", a  real San Francisco club where comedians such as  Phyllis Diller (I) (qv) and the Smothers Brothers  (Dick Smothers (qv) and Tom Smothers (qv)) performed. When  Julias boyfriend shows up, the comedian on stage is dressed like,  and performing one of the monologues of, Bob Newhart (qv), because  he is Newharts son.
