The answer to this nostalgic quiz is Robin Williams. The beloved comedian brought the alien Mork from the planet Ork to life, and his wild energy made the character one of the most memorable figures of 1970s television.

Why Mork Became a Television Icon
Mork first appeared in a two-part episode of Happy Days in January 1978. The character was so popular that he soon received his own spinoff series, Mork & Mindy, which premiered that same year on ABC. Williams played an eccentric alien sent to Earth to study human behavior, and his unpredictable humor quickly won over audiences.
Williams Brought Mork to Life
Williams was famous for his rapid-fire improvisation, and Mork gave him the freedom to jump between voices, physical comedy, and surprising character moments. His signature greeting, “Nanu Nanu,” became a catchphrase that viewers still remember decades later. Pam Dawber co-starred as Mindy McConnell, the earthbound woman who took Mork under her wing.
A Career That Went Far Beyond Ork
The success of Mork & Mindy helped launch Williams into a legendary career across film and television. He later earned widespread acclaim for dramatic and comedic roles, and his work continues to inspire comedians and fans around the world. Mork remains one of the most fondly remembered characters of the late 1970s.
