" in reference to Buffy the Vampire Slayer . In an interview featured on the third season DVD , Whedon joked that the " Business School " episode and his former TV show were very similar because " Buffy [ ... ] was sad and depressing but ... it was funny . Especially when people died . And a lot of people do die in [ ' Business School ' ] . " But upon completing the episode , Whedon stated " That was just coincidence . But that 's how that happened . God , it was fun . " Whedon stated that he was surprised with the amount of input he was allowed with the script . " I wouldn 't say freedom to do things with it ... But way more input was asked for than I would have ever anticipated . " At Pam 's art show , the pieces which she was supposed to have painted didn 't suit Whedon . " I got to the set and saw Pam 's art , and I was like , ' This is not right . ' " Whedon said that he held up filming for over an hour until the staff was able create new pieces of art .
