How did Bill Cosby come up with Fat Albert?
Fat Albert first appeared in Cosby’s stand-up comedy routine “Buck Buck,” as recorded on his 1967 album Revenge. The stories were based upon Cosby’s tales about growing up in the inner city of West Philadelphia. In 1969, Cosby and veteran animator Ken Mundie brought Fat Albert to animation in a one-shot prime-time special entitled Hey, Hey, Hey, It’s Fat Albert. http://en.wikipedia.
