Two explorers in Africa with their guide and they are caught by cannibals. The cannibal chief tells them that they have beaten their old enemies and have many people to eat so if the three can make 20 inches of cock between them, he'll let them go. They get them out, the natives measure them and they just make 20 inches so the chief lets them go on their way. As they leave, one of the white men says; "lucky I had 10 inches". The other white man says; "lucky I had 8 inches". the asian guide says; "lucky I had an erection".
