I've heard it. Kinda like Jerry Seinfeld without the breathy "h" on his "whhhyyy?". He could add the Jerry-isms, and sound just like him.
Not a man who ever permeated to the UK. I only know him as Sidney Bernstein from the Beverley Hills Cop movies, but those scenes made an impression.
He was the only good thing in Ford Fairlane. Not the guy I want to get stuck on a cruise lifeboat with, but if I am ever up for adoption he can be the person to give me away. A little bit of his comedy was scarring and long remembered. RIP.
