 " Eat , Pray , Queef " was written and directed by series co @-@ founder Trey Parker . It first aired on April 1 , 2009 in the United States on Comedy Central . Although Parker and fellow co @-@ creator Matt Stone acknowledged it was a particularly juvenile episode , Parker said it was his favorite show of the season to produce . He said , " I seriously never laughed as hard doing retakes , just going shot @-@ by @-@ shot , sitting there in the editing room laughing . " During the writing process , the female producers and employees with the show found the script largely unfunny , disgusting and offensive . They reportedly claimed vaginal flatulence would not bloom into a proud women 's movement as it did in the episode , but Parker and Stone insisted that was what made the concept even funnier .
