 While filming , Steve Carell and Tim Meadows improvised a lot of their dinner scene , but most of it never made the final cut . One improvised scene that did make the final cut was the " Baby Back Ribs " song . In an interview , Jenna Fischer said that the rooftop scene was her favorite to shoot . Fischer recalled that " there was a very small crew up on the roof and they had the cameras really far away . " After the main shooting ended , producers decided to do a re @-@ shoot to explain the " Dwigt " situation clearly and concisely . The kiss between Michael and Jan was rehearsed and filmed " many , many , many times " , according to B.J. Novak . While editing the kiss between Michael and Jan , Greg Daniels brought many people into the editing room to see if they thought the kiss was too long or not long enough .
