Commiserating with Joseph Gordon-Levitt

Have you seen the film 50/50?  It's good.  I think really good.  (Get the Kleenex) And admittedly OK, it's vulgar, but hey it's Seth Rogan + Seattle, what would you expect?

There is this one scene in the movie when I literally laughed out loud, totally getting the interchange between Levitt's character, Adam Lerner when he meets his therapist, Katie McCay for the first time.  McCay is played by Anna Kendrick.  In this scene he is surprised to find a young woman as his therapist and they have the following conversation:

Adam:  "I'm sorry.  How old are you?"
Katie:  "Twenty-four."
Adam makes the joke, "Who are you, like Doogie Howser?"
Katie: "Who?"

For the record, Jon Horne knows who Doogie Howser is.  What he may not be able to identify is Doogie's theme music.  A pity really.
