Dave is the leader of an African village in "Scammed Yankees" that tricks Carter Pewterschmidt into sending money to a "Nigerian Prince". Vowing not to permit himself to be scammed, Carter and Peter travel to the village to get the money back, to find that it has been used to help build needed infrastructure and buy supplies, with Carter being hailed as a hero.
However, still angry at being scammed, Carter orders everything his money was used for be destroyed. When Peter objects, Carter pays the villagers to lock him up and do the rest of his bidding. Lois finds out and arrives in Africa and saves Peter from being executed. Dave reveals the only way they can get the aid they need is through such scams. When Carter formally introduces Peter and Dave, Peter is surprised at the name, which is brushed off as not getting to know the villagers.
