Born in Boston, Rubin made more than 200 radio, film and television appearances over a span of 50 years.

A popular bit included Jack asking a series of questions that Rubin would answer with an increasingly irritated, "I don't know!"

He also guest appeared in an episode on the television series The Joey Bishop Show as the hypnotist, Max Collins.

As a result, Benny ended up giving the part to Eddie Anderson, and the porter character soon evolved into the famous "Rochester Van Jones".

In 1968, he appeared on Petticoat Junction as Gus Huffle, owner of the Pixley movie theater, in the episode "Wings".

Permabooks were designed with an unusual format of a paperback bound with stiff cardboard covers (with a "special wear-resistant finish") to simulate the look and feel of a hardcover book, and the company had previously published Best Jokes for All Occasions, edited by Powers Moulton.

[6] Rubin died of a heart attack at Cedars-Sinai Medical Center in Los Angeles on July 15, 1986.
