History class

During history class at a German school, a young boy raises his hand and asks:

"Teacher, is it true that cities in Russia have the longest streets in the world?"

Clearly perplexed, the teacher asks the boy,

"What led you to believe such an assumption?"

"Well, teacher," the boy answer, "my grandpa told me that he and his unit were crawling through one street in Stalingrad for three months and never reached the end of it."
