Jim Halpert (John Krasinski) is a paper salesman at the Scranton branch of Dunder Mifflin. He is a good guy, and very intelligent albeit unmotivated. Throughout the four seasons of the show and counting, Jim spends most of his time pining for Pam Beesly and/or engineering pranks at the expense of office-mate Dwight Schrute.
Jim: Um, is it me or does it smell like updog in here?
Michael: What's updog?
Jim: Nothing much, what's up with you?
Not enough for me? You are everything.Jim (to Pam)
