One of his friends, Boston bandleader Joe Rines, tried to persuade him to become a full-time comedian, but by this time, he was making a good living as advertising manager for Kane's Furniture. Einstein finally agreed to make an appearance on Rines' radio program; he created the Greek character of Nick Parkyakarkus for a skit on that show. The character was very well received by the listeners, and it ultimately led to the national networks' taking notice. Einstein got his big break nationally when he was first heard as a performer on Eddie Cantor's radio show in 1934.
