Of all the remembrances of Robin Williams online last night, the one from former Saturday Night Live star Norm MacDonald is among the most touching.
MacDonald shared an emotional memory of Williams boosting him up when he was a nervous young comic who was about to do his first show on Letterman.

It was my first stand-up appearance on Letterman and I had to follow the funniest man in the world. #RIPRobinWilliams
I was a punk kid from rural Ontario and I was in my dressing room, terrified. #RIPRobinWilliams
I was on the phone to a friend back home when the funniest man in the world ambled by. #RIPRobinWilliams
There was no one else on the floor. In shock, I told my friend who just walked by. Only the funniest man in the world. #RIPRobinWilliams
I guess he heard me say his name, cause in an instant he was at my side. #RIPRobinWilliams
He was a jewish tailor, taking my measurements. He went down on his knees, asked which way I dressed. #RIPRobinWilliams
I told my friend on the phone that the funniest man in the world was on his knees before me, measuring my inseam. #RIPRobinWilliams
My friend didn't believe me so I said, "Could you talk to my friend, sir. #RIPRobinWilliams
The funniest man in the world took the phone and for ten minutes took my friend's chinese food order. #RIPRobinWilliams
I laughed and laughed and it was like I was in a dream because no one else was there. No one. #RIPRobinWilliams
The place was out of Moo Shoo Pork, and there was nothing he could do about it. #RIPRobinWilliams
He angrily hung up on my friend and I was about to thank him when he said I hadn't even tried the jacket on. #RIPRobinWilliams
Then the funniest man on earth dressed me, a complete stranger, and i remember he ended with a windsor knot. #RIPRobinWilliams
He spoke mostly yiddish, but when he finished he was happy with his job and turned me to a mirror to present myself to me.#RIPRobinWilliams
No one witnessed any of this. No one. #RIPRobinWilliams
The funniest man alive was in my dressing room a good half-hour and was far funnier than the set I had to do soon.#RIPRobinWilliams
ll of a sudden it was, had to. #RIPRobinWilliams
When he left my dressing room, I felt alone. As alone as I ever remember feeling. #RIPRobinWilliams
Until today. #RIPRobinWilliams
Unacceptable. #RIPRobinWilliams
