Jim gets everything he’s ever wanted because of a rather confusing avant-garde movie, and because of the sheer contempt that Pam has over his Netflix queue.  To most people, impulse involved something simple—something normal—in an unplanned fashion. 

           Hey, we were going to sit around and watch TV tonight, but instead let’s go bowling.  How quirky and cute of us!   

But, apparently, when Pam Beesley gets bored, it’s a whole other sack of potatoes.  “I want to do something impulsive,” she said. 

Jim would remember those words years later as he recounts the story to their children—about how two people that took four years to get together managed to get married after only four months—all because of how much Pam hates Jim’s taste in movies.
