text:  The writing staff used their individual childhood experiences as inspirations to come up with much of the story lines for this episode . The idea for " <unk> Mouth " was inspired by creative director Derek <unk> 's experience " [ when ] I got in trouble for saying the f @-@ word in front of my mother . " <unk> said , " The scene where Patrick is running to Mr. <unk> to <unk> , with <unk> chasing him , is pretty much how it happened in real life . " The end of the episode , where Mr. <unk> uses more <unk> than <unk> and Patrick , was also inspired " by the fact that my [ <unk> 's ] mother has a sailor mouth herself . "
