Whenever I drive up to Wrigley Field (3 hours) I always play this game with people in the car. It's kills time and is very fun.
Someone names a baseball player. Then the next person (going clockwise or whatever way you want to go) has to say a name of a baseball player who's first name starts with the first letter of the last name of the player who was just named.
Example: Jose Contreras. The next guy now must say someone's name who starts with 'C'- Chad Tracy. Then the next guy- Tyler Walker and so on...
If you get a double letter like Barry Bonds, Sammy Sosa, then you reverse directions.
You can't say a name more than once.
That's about it. It's fun. Kills time and some of the names you come up with is fun.
