Cartman begins to wonder why all the kids at school have fathers but him. When he asks his mother who his real father is, she tells him about the night of the drunken barn dance, when he was conceived. Unfortunately, Mrs. Cartman had sex with just about every man in town that night. Dr. Mephisto can perform a DNA test to determine who the father really is, but the test costs $3,000. How can Eric raise the money to learn the truth? Written by Jean-Marc Rocher <>

Part One Of An Exciting Two Parter!
29 July 2012 | by (United Kingdom) – See all my reviews

Cartman's Mom Is A Dirty Slut was the very first episode that was a two parted episode which Trey Parker And Matt Stone made. The plot evolves around Cartman who asks his Mom who his father is. The South Park Gang go on a quest to find out who Eric Cartman's Father is and finding out information about The Drunken Barn Dance that happened on the exactly same night as Cartman's Mother's pregnancy. It is a great episode which ends the season on a cliffhanger and The Terrance And Phillip In Not Without My Anus episode premiers at the beginning of Season Two! If you are a South Park Fan and you have not seen it yet, please watch it! You will not be disappointed!

Overall Rating: 8/10!

Overall Rating For South Park Season One: 17/20!
