Professor Hadari was teaching advanced map reading in his earth sciences class at the Hebrew University of Jerusalem. After explaining about latitude, longitude, degrees and minutes Professor Hadari asked, "Suppose I asked you to meet me for lunch at 23 degrees, 4 minutes north latitude and 45 degrees, 15 minutes east longitude...?"

After a moment of silence, a student named Itzik volunteered, "I guess you'd be eating alone."
