A cannibal joke

The British, Americans and Japanese are on the same plane; Accidentally crashed and landed in Africa (it is said that cannibals sometimes haunt). Unfortunately, the three of them were caught for dinner before they could escape. When they frowned and watched the cannibals dance, they saw the leader come to inspect three sumptuous dinners ... The three of them tried to communicate with the chief with luck (of course not with quick translation! ) They expressed it in body language and asked the chief to let go ...; The indigenous chief agreed, but he gave them a question to embarrass them. His topic is: let three people take out the penis and measure it. If it adds up to 19 cm ... release it! At this time, the British took the initiative to ask for a measurement first. Wow! Seven centimeters! Then there is 10 cm in the United States. Finally, the Japanese are two centimeters (ha! Please calculate: 7+ 10+2 = 19, right? ! The chief kept his promise and let them go. The three men ran and crawled out of the cannibal village and ran for their lives! ! Go! Go! The Japanese took a deep breath and said, Hoo! What a Li Jiazai. Just as I was measuring the length, I suddenly got excited somehow!
