1. Fair - A bounding ball which bounces over the base at 3rd base and lands fair is a _____________ ball. How many times have you seen this one screwed up?

2. Foul - Fly ball to left field near the line. F7 touches the ball over fair territory but drops the ball. Ball lands in foul territory. What do you rule?

3. Interference - This one is complicated enough as it stands.

4. Obstruction - This one is also complicated enough as it stands.

5. Infield Fly - Most players have no clue how this rule actually works and many umpires still don't know it.

These 5 things will occur multiple times in almost every single game. Knowing these 5 things backwards and forwards, how to apply them and how to explain them to a coach or player can keep you out of a lot of trouble. And because they happen quite regularly throughout each and every game knowing them just makes sense.
