I'll bet he can do the pre-game announcements (culminating with "Please pay these prices and please pay....noo mooore") in his sleep with no script in front of him. It seems that it hasn't changed in over 35 years since I've been going to games.
I really like hearing "met by a HOST of Volunteers!" on occasion.
One complaint though: with all the other renovations to the stadium, I do wish they would install a newer, clearer, more effective sound system and speakers throughout the stadium. It is often difficult to hear or distinguish what's being said, not just with his calls during games, but especially the jumbotron featured videos.
