Analysts

An American mathematician returns home from a conference in Moscow on real and complex analysis. Immigration officer at the airport glances at his landing card and says: "So, your trip to Russia was business related. What's the nature of your business?"

"I am a professor of mathematics."

"What kind of mathematics are you doing?"

The professor ponders for a split second, trying to come up with something that would sound specific enough without making the immigration officer suspicious, and replies: "I am an analyst."

The immigration officer nods with approval: "I think it's great that guys like you go to Russia to help those poor ex-commies to get their stock market on its feet..."
