This is the first two part episode of South Park.Only this one's first part is the season finale and the second part is the second episode of the second season.Instead of making it the premiere, Trey and Matt made a Terrence and Philip special entitled "Not Without My Anus"(you can actually see the trailer for it during this episode when they are watching TV).Anyway this episode has the boys noticing Cartman skipping school.So they go and see him in his backyard playing tea-party with his stuffed animals.The boys videotape the behavior so Mr Mackey can study it but instead send it to America's stupidest home video's for a prize of $10,000. Cartman has been acting strange because he wants to know who his father is.His mother happens to be a "slut"(hence the title) and got drunk at a barn dance eight years before and does not remember who the father was.She does remember a man named Chief "Running Water".He tells Cartman that it was Chef who she last saw him with and Chef says it was Mr.Garrison afterwords.Cartman then goes to a bar and finds out that almost everybody in town(even the women) have slept with Cartman's mom.Stan and Kyle use the second place money they got(the first place went to Stan's Grandpa filming Kenny's demise) to get a DNA test from everybody in town.That is where the two parter ends.This was a fairly funny and good season finale.The april fools joke episode "Not Without My Anus" does not usually air in syndication but I think it should.It's a decent episode.
