Is there something wrong with me?

Am I missing some vital part of my brain?

I don't get Casablanca. I spend the last ten or so minutes shouting "Shoot him! Shoot him & go to America!" at the screen. Which pisses off my boyfriend no end, because although he sounds like a Londoner, he is in fact a cunningly disguised Czechoslovakian Cockney & tends to take it rather personally.

I also read far too much into the 'beautiful friendship' bit at the end, but we all know I have a filthy mind.
