 Jim Halpert ( John Krasinski ) and Pam break off their respective evening plans to enjoy an impromptu dinner on the roof and watch Dwight and Kevin fool around with fireworks . The next day , Jim jokes about their " first date " , and Pam , in an unexpectedly blunt tone , tells him it was not a date . Surprised and obviously disappointed , Jim makes an unwise comment that at least he didn 't leave her at a high school hockey game , in reference to Pam 's earlier revelation of what Roy had done on her worst date ever . Pam is clearly upset and gets up to go send some faxes , leaving it awkward between her and Jim , who tries unsuccessfully to apologize .
