In 1987 they joined the writing staff on It's Garry Shandling's Show,[2] and in 1989 they wrote an episode for The Wonder Years called "Math Class".

Seinfeld mentioned that he and co-creator Larry David were initially worried about Gammill and Pross' writing style, as the pair created stories that were a "level of silliness" that the show had never gone to before.

Ultimately the worry was unfounded, as the pair ended up writing some of the most famous Seinfeld shows during the series' run.

They are also given story credits on the 2007 comedy Full of It, in which a teenage boy is forced to live out the lies he had told in order to become popular.

Dialogue in Ghostbusters II refers to a "Gammill and Pross Infant Acuity Test" though their contribution to the film is unknown.
