Two engineering students meet on campus one day. The first engineer calls out to the other, "Hey nice bike! Where did you get it?" "Well," replies the other, "I was walking to class the other day when this pretty, young coed rides up on this bike. She jumps off, takes off all of her clothes, and says 'You can have anything you want!'" "Good choice," says the first, "her clothes wouldn't have fit you anyway."
The teacher of the earth science class was lecturing on map reading.
After explaining about latitude, longitude, degrees and minutes the teacher 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 confused silence, a voice volunteered, "I guess you'd be eating alone."
