The broadcast date of the subsequent episode, "Cartman's Mom Is Still a Dirty Slut", was moved up in response to the complaints."Terrance and Phillip in Not Without My Anus" received generally mixed reviews, with some commentators criticizing Parker and Stone for "duping" their viewers, and others praising them for taking the risk.
"Terrance and Phillip in Not Without My Anus" is the second season premiere of the animated television series South Park.
The 14th overall episode of the series, it originally aired on Comedy Central in the United States on April 1, 1998.
The episode follows the two title characters, a duo of Canadians who attempt to save their country from the dictator Saddam Hussein while performing repetitive toilet humour.
Unbeknown to them, the plan was partially set up by their rival, Scott, a critic who is often displeased by their random jokes of flatulence.
A caption wishes the viewers a happy April Fools' Day.
The drama itself opens in a courtroom in Canada, with Terrance on trial for the murder of a local doctor; Phillip is his lawyer while Terrance and Phillip's sworn nemesis, Scott, who has had a long hatred of the duo's toilet humour, is acting as the prosecutor.
Scott uses a group of seemingly airtight exhibits such as a hammer, a piece of Terrance's shirt, and an incriminating haiku to prove Terrance's guilt, while Terrance's defense consists of nothing but a long string of fart jokes.
The script was written by series co-creators Trey Parker and Matt Stone, along with writer Trisha Nixon.
The episode is one of the favorites of Parker and Stone.
The episode was an April Fools' Day prank on South Park fans, who were waiting to learn the identity of Cartman's father after the cliffhanger ending of the first season finale, "Cartman's Mom Is a Dirty Slut".
The prank angered viewers, and resulted in 2,000 angry e-mail complaints to Comedy Central within a week of the original broadcast.
