"The friend that I based Heffer on was adopted, and it all played into his total personality"

This quote by Joe Murray is referring to the character Heffer from the cartoon Rocko's Modern Life. Heffer was an obese, adopted steer who was always entering into trouble. The quote suggests that the pal Joe Murray based Heffer on was also embraced, which this played a role in the advancement of Heffer's character. Adoption can be a difficult experience for many individuals, and it is likely that the buddy's experience of being adopted had a considerable effect on his character. This might explain why Heffer was so awkward and naive, as he was likely attempting to understand his own adoption experience. It is likewise possible that the buddy's adoption experience was a source of humor for Joe Murray, which he then used to develop the character of Heffer. Eventually, this quote suggests that the pal's adoption experience was a significant influence on the advancement of Heffer's character.
