It was all going so well.

After an entire decade of sex, drugs and rock & roll, the public had grudgingly learned to accept the idea of free love and recreational pharmaceuticals.

But that was before the arrival of Charles Manson, now simply known to historians as "that asshole."

After an extended round of group sex and drug use, Manson and his associates, now simply known to historians as "those assholes," entered the home of director Roman Polanski and his pregnant wife, actress Sharon Tate.

One dead pregnant actress later, a whole generation's decade-long struggle to smoke dope and fuck your friends hello went down the proverbial drain. This single brutal act spelled the beginning of the end of the sexual revolution, made the legalization of drugs untenable, and set into motion historical forces that would eventually subject all humanity to eight years of Nancy Reagan.

On behalf of all humanity, thanks.
