Animation on shows like Animaniacs, The Sylvester & Tweety Mysteries, Detention, Histeria!, ¡Mucha Lucha!, and Krypto the Superdog. Both of them later thought on a idea when having a friend who told Timothy Cahill, when he was in first grade, he attended a experimental school that had a monkey in the science area; and that friend of theirs used to go hang out with the monkey. Tim Cahill found that story hilarious that he thought that it would be a great idea to adapt it in a cartoon, despite which, the characters aren't based off of real people, but it was adapted into different types of people like the stoner (Slips), strong silent type (Windsor), the girl who suddenly got taller over summer (Ingrid), and more.

The show was what Tim had in his back pocket beforehand in the 1990s with the pitch actually being the second choice of what they wanted to do. The show was pitched to Cartoon Network in 2001 under the name "The Zoo, but in 2002, the title was changed to its current title, "My Gym Partner's A Monkey" to give it a comedic title. The concept of the show began in 2003 with a pilot and in 2004, the show was given another pilot that features the final designs for the show.

He is seen very often with his best friend, Windsor Gorilla.
  • Windsor Gorilla- A dispassionate, but thoughtful and wise lowland gorilla, who is seen a lot with Slips Python.

He has liticaphobia, a fear of lawsuits.
