Ball In A Cup 

Mexico's Favorite Toy For over 1000 years!
The objective is to catch the ball in the cup.
No need to worry if you miss, as the ball is attached to a string that is attached to the cup!
Storage is as easy as catching a ball in a cup!

Ball in a cup, ball in a cup, it's a ball in a cup!

Ball in Hand 

In various types of pocket billiards (pool), "ball in hand" refers to a player's right to place the cue ball anywhere on the table. Getting "ball in hand" means that the opposing player (the offending player) committed a foul, an example being a table scratch.

"Ball in hand," he yelled, throwing the cue ball sheepishly on the table after fouling.
