South Park - Episode 0308 - Original Air Date: 21st July 1999.
This South Park episode was write by Matt Stone and Trey Parker.
This South Park episode is happening in the same night as episode 307 and episode 309
After dropping Shelley off at Cartman's home, the Marshes and Stan are off to a party at the home of School Counsellor Mr. Mackey. Stan is upset that he has to go and becomes even more angered when he is locked in a room with nerdy "Melvin" classmates that he does not like: Pip, Butters, and Dougie. The three insist on playing Charlie's Angels, and an unenthusiastic Stan uses the game to find a way out of the basement to an upstairs bedroom where there are cookies and TV.
Meanwhile, Mr. Mackey's house is surrounded by the FBI under the impression that there's a cult gathering in the house.
In this episode Butters speaks for the 1st time in the South Park show. He has previously been seen in many episodes, but up until now was silent.
This entire episode is an obvious spoof on the 1993 stand-off between federal agents (ATF and FBI) and cult leader David Koresh and his Branch Davidians cult in Waco, Texas.
