In 1991, Green rose to fame in a Rally's "Cha Ching" commercial,^[9][10] which earned him an appearance at a New Orleans Saints game.

Developing the character with James Gunn, Green did an impression of Danny DeVito, "being sort of a gruff and cynical sarcastic character [who] doesn't know what the Earth species of duck even is and doesn't think of himself that way and is offended by that generalization."^{[19][20][21][22]}
