Its success was due in no small part to the all-star cast of voices. Among them was Robert Guillaume as the voice of Rafiki the shaman.
Rafiki the shaman repeats the phrase “Asante sana, squash banana, we we nugu, mi mi apana” which Disney claims is a Swahili dialect for “Thank you very much, squash banana (already in English), you are a baboon and I am not.”
Due to the words running together, some people have suggested that he was actually saying something rather rude, but he is not (much like the rumor about the song Louie Louie in the 1960s, which was also untrue)
Rafiki is a primate with characteristics of both a mandrill and a baboon.
