Josh Weinstein (later known as J. Elvis Weinstein) was one of MST3K's original writers and cast members. He portrayed Dr. Laurence Erhardt, aide to Dr. Clayton Forrester, and was the original voice and puppeteer of Tom Servo and Gypsy. He also voiced Crow in the unaired KTMA pilot. He departed from the show at the end of its first season, and adopted the name "J. Elvis Weinstein" to avoid confusion with a Simpsons writer named Josh Weinstein.
From 1999 to 2000, Weinstein was a writer and executive producer on the cult-favorite Judd Apatow NBC series "Freaks and Geeks", which also featured Trace Beaulieu and Joel Hodgson in supporting roles.
In fall of 2014, Weinstein appeared in the music video comedy short The Frank along with other MST3k members. It was made available exclusively for DVD.
- "I met Joel after he came back to Minneapolis. I was 15 and had just started doing stand-up. He had an air of specialness about him, because he had been in the big time. He was definitely an artist among comics."
- "We eventually realized, hey, this might be funnier if we had some jokes in our back pocket."
- (on choosing the moniker "J. Elvis") "I decided on it because when I joined the writer's guild there already was a Josh Weinstein, and I gave myself the Elvis because I loved that it gave me the initials J. E. W. and also somewhat inspired by being a fan of Elvis Costello, but mostly it's about J. E. W."
- (on the difference between geeks and nerds) "Geeks will talk to us, nerds find us too weird."
