 Canadian animator and creator of The Ren & Stimpy Show , John Kricfalusi , guest animated the couch gag for the episode . This was the second time The Simpsons had chosen a guest director for its opening sequence , following the previous season 's episode " MoneyBART " , which was guest directed by British graffiti artist and political activist Banksy . Previously , Kricfalusi had criticized The Simpsons staff in the show 's early years by saying that " the show succeeded despite the writing " and similarly derogatory comments . The producers responded with the fourth season episode " The Front " ( 1993 ) , in which The Ren & Stimpy Show is nominated for a cartoon award . During the award ceremony , the clip from the nominated episode is merely a black screen with the text " Clip not done yet " , a comment on the slow production time of the show . The show was mentioned again in the season six episode " Another Simpsons Clip Show " ( 1994 ) , when Lisa claims that Ren & Stimpy recycles animation to make new episodes , while referencing Itchy & Scratchy 's habit of doing the same . Despite this , Kricfalusi changed his tone in an interview with Aaron Simpson in 2007 and claimed that The Simpsons made it easier to do more edgy work : " Well it started with Bakshi ’ s Mighty Mouse : The New Adventures and Pee Wee Herman . Those were kid shows , but with layers of perversion in them . Then The Simpsons came along and did edgy material in prime time cartoons . "
