In the scene after the huge fight with the Buddists, Jack Nicholson speeds off in his Land Rover and cuts into traffic to get away from the monastary. If you look three cars back there is a state trooper weaving through both lanes to make sure the set is closed. He stays visible throughout the scene.
In the baseball scene, Rudolph Giuliani yells, "You can do it!" which is a regular line in Adam Sandler films. Rob Schneider says it in The Waterboy, and then again in Little Nicky. Sandler himself says the line in Schneider's The Animal.
