Some of the more curious entries:
10. Youppi! -- Really? I'm surprised anything from the Expos makes the list, much less a furry mascot.
11. Fans Running Out Onto The Field (after a team clinches a title) -- Um, not in this day and age, or has someone forgotten the Ligues, Jr. and Sr.
21. Bullpens Not in Foul Territory -- Not in my book. Keep them away from the field.
24. Unbalanced Schedules -- And when we had unbalanced schedules, people were bitching that division rivals didn't play enough.
25. Bullpen Carts -- I never understood the charm of these. Like the pitcher couldn't get from the bullpen to the mound under his own power?

6. Listening to Baseball On The Radio -- "Once upon a time, before Sirius and XM and MLB.com." I kind of get his point about the romanticism of finding a game broadcast from a faraway signal surrounded by static, but the author is aware that Sirius/XM and MLB.com allow you to listen to any game you want, with the local announcers, right?
