It's no surprise that Seinfeld defined an era and is considered to be one of the greatest shows ever. After being on the air for nine seasons, it's almost impossible to not hear about this classic sitcom, and not its star, comedian Jerry Seinfeld. Born on April 29, 1954, in Brooklyn, New York, the New York Mets fanatic has found more success after his show ended in 1998. There are so many little things that people would never guess about the comedian. How much do you really know about this guy anyway?

The New Yorker took odd jobs to pay the rent during his early days in comedy. In some jobs, he used it as an excuse to try out new material. For instance, he sold light bulbs over the phone with his friend Mike Costanza.

Later on, Seinfeld found himself waiting tables, but quit after he landed a gig emceeing at the Comic Strip. That was only the beginning for the aspiring comedian.
