A good read is his memoir,
Soft Pretzels With Mustard. Hilarious, and sad, too.
I remember a story he told about being on the subway, sitting on a newspaper. A man came up to him and asked him if he was reading the paper. Without missing a beat, Brenner said, "Yes, I'm nearsighted." stood up, turned the page, and sat back down again.
He will be missed.
