Rob Paulsen has said that the most often asked question he receives is whether or not he still knows the words to "Yakko's World". He will often perform it live for fans at conventions.
Yakko's world was out of date when this aired in September 1993. It includes Czechoslovakia, which split into Czech Republic and Slovakia January 1, 1993. Russia is drawn on the map as the Soviet Union, which split in 1991, and none of the other former Soviet republics are included. He included Burma; that country officially changed its name in 1989 to Myanmar, though both names are still in use. It correctly described Germany as "now in one piece", that country reunited in 1990 and was still a work in progress in 1993. He named Kampuchea, which is usually called Cambodia in the West.
