This is done by:
1. showing up to class first, or before too many people get there.
2. placing your belongings on a strategically selected desk and leaving.
3. coming back to the class with 1-2 minutes left before the start.
4. hopefully your new seatmate is a cute girl, if so, you have just successfully completed the hot baby surprise.
Don and Jill have been going out for 3 years now. Don met Jill after the two struck up conversation during a class in college. They had met after Don successfully executed the hot baby surprise.
