- When you talk about "Going to second base" with a girl, you mean you went to the stadium and ran halfway 'round the infield
- When you remember more than 5 starters for any pre-1995 Seattle Mariners team (or pre-1990 Astros team).
- When you've gone to any city just to see the stadium.
- When you place a radar gun over the baby's crib.
- When you can calculate a pitcher's season ERA to the thousandths place at any start after the All Star Break
- When you name your child Willie, Mickey, or Duke (Or Tinker, Evers, or Chance for Cubs fans)
- When you respond that you're not sure, but think Holden Caulfield just might have been the backstop for the '61 Mets
- When you argue for the elimination of the maximum age for major league batboys
Ahh, baseball...what bliss! Welcome to spring training, folks.
