Mrs Robinson

There is a movie called "The Graduate"
About a older woman named Mrs. Robinson, sleeping with a younger man.
Staring Dustin Hoffman.
Now it's very common to use "Mrs Robinson" to any woman in a similar situation. I'm sure Ты have seen parodies of it before :)

Also in "Lets Kill Hitler" River says "Hello Benjamin" to The Doctor. Benjamin was the name of Hoffman's character in The Graduate.
