David Alan Grier: Stopped Smoking Reefer

I stopped smoking reefer because I started thinking, if great men throughout history had smoked reefer, no tellin what would have happened. Like if somebody like Martin Luther King Jr. had smoked reefer, he would have been giving speeches like, I had a dream, but the hell if I could remember what it was about. It was either about freedom or Fritos.

First jukebox installed

In 1889, the first jukebox was installed when an entrepreneur named Louis Glass and his business associate, William S. Arnold, placed a coin-operated Edison cylinder phonograph in the Palais Royale Saloon in San Francisco. The machine, an Edison Class M Electric Phonograph with oak cabinet, had been fitted locally in San Francisco with a coin mechanism invented and soon patented by Glass and Arnold. This was before the time of vacuum tubes, so there was no amplification. For a nickel a play, a patron could listen using one of four listening tubes. Known as “Nickel-in-the-Slot,” the machine was an instant success, earning over $1000 in less than six months.[Image: From U.S. Patent No. 428,750 "coin actuated attachment for phonographs" issued to Glass and Arnold on 27 May 1890]
