PA4: Citizens on Patrol
Arguably the best in the series.
From the trivia:
Tony Hawk said this was the only job he was ever fired from. Most of the stunt doubles were from the Bones Brigade because their manager, former pro skater Stacy Peralta, worked as a second unit director on the film. As it turned out, Hawk was replaced as a stunt double for David Spade because he was too tall.
