Yes indeed. Terrible news for sure. He was only 61, which is way too young for anyone.
If his name doesn't sound familiar, look at Dan's link or Google him- chances are you know who he is, and have seen him in something. He was on SNL, he was on My Name is Earl, he had a Netflix show of his own, he was in several Adam Sandler films, had a few of his own, played the gelatinous blob on the Orville.....
I am going to miss him. He was one of the greats for sure.
