And they were both topless! Gasp.
But it's heartwarming when everyone who knew him speaks nothing but kind words about him.
And that's all Henry Winkler had to say upon news about his former Happy Days co-star's passing.
He opened up about just what it was like to be in the presence of Robin playing Mork while on set, seeing him work in the most magical way:
"Here I am playing this man of very few words and I'm watching brilliance explode like fireworks every 10 or 15 seconds."
He added about Robin's comedic power during scenes:
"What ever you said, he inhaled out of the air and then threw it back at you. There was not one time it came out the same. There was not one time it was not truly, endlessly and fervently funny. You saw it and your mouth dropped. You couldn't believe it. I've worked with a lot of people and there is and was no one quite like him."
And more than that, while working together on Mork & Mindy, it seems everyone realized they were in the presence of someone special as Henry revealed the notes that were soon left on the scripts:
"'Robin will do something here.' After a while, I don't think they even bothered writing comic pieces for him because he was uncontainable in this universal way. He was touched. He was given something."
We're sure Robin will live on through his many legendary films and TV shows.
