Two men are approaching each other on a sidewalk。 Both are dragging their right foot as they walk。

两个人在人行道上分别拖着自己的右腿,相向而行。

As they meet, one man looks at the other knowingly, points to his foot and says, Vietnam, 1969。“

他们相遇了,一个人理解地看着另一个人,指着自己的腿说:“1969年,越南。”

The other points his thumb behind him and says, “Dog crap, 20 feet back。”

另一个人竖起了大拇指,说“再走20英尺,狗屎。”
