History class in a small Jewish town in Russia. The teacher asks: "What great event, consequential for the history and culture of the Russian people took place in 1799 ?" Complete silence. "Well, children," continues the teacher, "it was in 1799 that the greatest Russian poet, Alexandr Sergeevich Pushkin, was born." "Ahhh..."
Next question: "What other momentous event, extremely important for Russia, took place in 1812 ?" Again, dead silence. "Really, children don't you remember this one ?" insists the teacher. Prompted by which, little Itzik raises timidly his hand and opines: "It was the Bar-Mitzvah of the great Russian poet, Alexandr Sergeevich Pushkin."
