Here's my second post about trivia in Pulp Fiction. Remember the part in the "wax museum with pulse" diner where Vincent takes his boss's wife Mia for a dinner and good time?
Remember what Mia ordered? a 5$ shake. And there was a looong discussion after that about it.
Notice that the waiter asks her if she wants it "Martin and Lewis or Amos and Andy?" He is referring to two comedy duos - Dean Martin and Jerry Lewis, two white men; Amos and Andy, two black men. Basically, he is asking her if she wants a vanilla shake or a chocolate shake. She has vanilla.
And here's the scene!
