 Originally , Parker and Stone considered making a full @-@ length episode of The Queef Sisters . The duo had pulled a similar stunt with the second season premiere . Instead of the expected follow @-@ up to " Cartman 's Mom Is a Dirty Slut " , in which the identity of Cartman 's father was to be revealed , Parker and Matt Stone showed the episode " Terrance and Phillip in Not Without My Anus " , a Terrance and Phillip @-@ centered episode as an April Fools ' Day prank . Since " Eat , Pray , Queef " was coincidentally also set to air on April Fools ' Day , they considered a similar joke revolving around Katherine and Katie . However , since " Terrance and Phillip in Not Without My Anus " infuriated South Park fans at the time , they decided not to do it and wrote a full script for " Eat , Pray , Queef " instead . The original prank is referenced in the episode , when The Canada Channel announces that it will not air a much @-@ anticipated part two episode of Terrance and Phillip , and instead will show the Queef Sisters as an April Fools ' Day prank . The angry reaction from the boys mirrors the real @-@ life fan reaction to the South Park second season premiere .
