The world lost Robin Williams yesterday, a prolific actor and comedian who entertained us for the last 35 years.
While he was best known for his movie performances, one of which won him an Oscar, the actor made his initial mark on television, both as a stand-up comedian and with his iconic role as Mork from Ork, starting on Happy Days and spinning off to Mork and Mindy.
As Mork, he gave to the world words from the Orkan language - a greeting, "Na-nu Na-nu;" a curse word, "Shazbot" and KO instead of OK (Did you ever wonder how that became a thing?).
Williams had hundreds of appearances in stand-up specials, benefits and on talk shows. In addition to his starring role on Mork and Mindy from 1978-1982, he most recently anchored The Crazy Ones on CBS, opposite Sarah Michelle Gellar and James Wolk.
He was nominated for eight Primetime Emmy Awards over the decades and won two.
As we mourn the actor, here's a look at some of Williams' more memorable TV roles:
